Overview of Edgerouter X VPN capabilities
I’ll break down the main options you’ll likely use on the Edgerouter X:

• Site-to-site IPSec: persistent tunnels between two networks, usually with a static public IP on both ends.
• Remote access IPSec L2TP/IPsec or IKEv2: allows individual users to connect securely from anywhere, ideal for remote workers.
• OpenVPN: widely supported, easy to client-create, can run as a service on the router, good for legacy clients.
• WireGuard: modern, lean VPN with fast handshakes and simple configuration, excellent for mobile and desktop clients.

Prerequisites and planning
Before you touch the config, gather these details:

• Public IPs for both ends static is best; dynamic can work with a DDNS service.
• Internal subnets for both networks e.g., 192.168.1.0/24 and 192.168.2.0/24.
• DNS strategy for remote networks use internal DNS or public resolvers.
• Firewall policies you’ll need allow VPN traffic, keep WAN ports secure.
• Administrative access to the Edgerouter X SSH or GUI and a backup plan in case you lock yourself out.

Network and security prerequisites

• Firmware: Ensure you’re running a recent EdgeOS version that supports IPSec, OpenVPN, and WireGuard on the Edgerouter X.
• Public-facing ports: IPSec typically uses UDP 500 and 4500, and IPsec NAT-T. WireGuard uses UDP 51820 by default, though you can customize.
• DNS: Decide whether VPN clients will use the VPN server’s DNS or a dedicated resolver.
• Authentication: For IPSec, pre-shared keys PSK or certificates. For OpenVPN/WireGuard, username/password or key pairs.
• NAT traversal: If behind double NAT, consider using a public endpoint or a relay setup, though IPSec typically handles NAT-T.

OpenVPN and WireGuard have their own pros and cons for site-to-site setups, but most people will use IPSec for fixed tunnels. If you want to enable OpenVPN or WireGuard for additional remote access, see the next sections.

Remote Access IPSec setup guide
Overview

• This is for users who need to connect to your network from remote locations securely, typically using IPsec with L2TP or IKEv2.

Step-by-step guide IKEv2/IPsec remote access

1. Enable IKEv2 on both ends and define a remote access pool addresses assigned to clients when connected.
2. Create a user or certificate-based authentication method.
3. Configure L3 VPN policy to allow remote clients to access internal subnets.
4. Create firewall rules to permit VPN traffic and block unsolicited access from the internet.
5. Generate client profiles or certificates for users.
6. Distribute client configurations to users and test with a VPN client.

OpenVPN setup guide
Why consider OpenVPN?

• Wide compatibility with older devices
• Fine-grained access control
• Works well behind NAT with proper port forwarding

How to enable OpenVPN on Edgerouter X

1. Install OpenVPN package if available on your EdgeOS build, or use a Docker container if your device supports it not common on Edgerouter X without extra steps.
2. Generate CA, server certificate, and client certificates using OpenVPN’s easy-rsa workflow or a similar tool.
3. Create an OpenVPN server configuration:
   • Port: 1194 default
   • Protocol: UDP
   • Cipher: AES-256-CBC or AES-256-GCM
   • TLS/auth: Enable HMAC authentication
4. Configure client config files with remote server address, port, and certificates.
5. Set firewall rules to allow OpenVPN traffic.
6. Start the OpenVPN service and test with a client.

WireGuard setup guide
Why WireGuard?

• Simplicity: small, fast, straightforward configs
• Superior performance on modern networks
• Easy roaming and reconnect behavior

How to set up WireGuard on Edgerouter X

1. Install WireGuard package if available in EdgeOS. If not, you may need to rely on a supported build or a Docker-based workaround.
2. Generate private/public key pairs for the Edgerouter X and each client.
3. Create a WireGuard interface wg0 with a listening port default 51820 and assign an internal IP e.g., 192.168.99.1/24.
4. Add peer configurations for each remote client:
   • Public key
   • Allowed IPs the client’s VPN subnet, e.g., 192.168.99.2/32
   • Persistent keepalive optional, e.g., 25 seconds
5. Firewall rules to allow WireGuard traffic and to route traffic between the VPN and internal networks.
6. Test connectivity between a client and the internal network. Use ping and traceroute to verify paths.

Advanced routing and firewall rules

• Split tunneling vs. full tunnel:
  • Full tunnel routes all client traffic through the VPN, which is common for site-to-site and some remote access setups.
  • Split tunneling lets clients access the internet directly for non-sensitive traffic, reducing VPN load.
• NAT considerations:
  • If the VPN uses private subnets that overlap with LANs, you’ll need NAT or policy-based routing to prevent conflicts.
• Firewall rule examples GUI or CLI:
  • Allow VPN traffic on WAN interface
  • Allow VPN traffic to internal subnets
  • Drop non-VPN inbound traffic from WAN
• DNS and name resolution:
  • Decide whether VPN clients should use internal DNS servers. You can push a DNS server address to clients or use a split-horizon DNS approach.

Performance tuning and monitoring

• Use AES-256-GCM when possible for better throughput and security, especially on WireGuard or IPSec with modern endpoints.
• Enable NAT-T to traverse NAT devices smoothly in IPSec.
• Check VPN SA Security Association lifetimes; too aggressive values can cause frequent rekeying and drops.
• Monitor with:
  • show vpn ipsec sa CLI
  • Routing tables to confirm routes are correctly added
  • Ping tests across VPN tunnels to measure latency and packet loss
• Power and heat management:
  • Edgerouter X runs hot under heavy VPN load; ensure adequate airflow in tight enclosures.

Troubleshooting checklist

• Tunnel not established:
  • Confirm public IPs and port forwarding are correct
  • Verify PSK or certificates match on both sides
  • Check Phase 1 and Phase 2 proposals for compatibility
  • Ensure the remote network subnets are correct
• Clients cannot reach internal resources:
  • Verify routing on both ends to ensure internal subnets are reachable via the VPN
  • Check firewall rules for allowed traffic
  • Confirm DNS resolution for internal hosts
• Performance issues:
  • Review MTU settings; IPSec often benefits from a slightly reduced MTU
  • Turn on logging for VPN and check for dropped packets or rekey events
  • Consider upgrading to WireGuard for higher performance
• Common NAT issues:
  • Overlapping subnets require NAT exemptions or custom routing rules
  • Ensure VPN traffic is not being NATed away from the tunnel

Common mistakes to avoid

• Using weak PSKs or self-signed certificates without proper management
• Overcomplicating the topology with unnecessary nested tunnels
• Forgetting to update firewall rules after adding a VPN tunnel
• Not testing with real clients or devices representing typical network conditions
• Ignoring DNS resolution needs for VPN clients

Recommended real-world pattern and example configurations

• Simple site-to-site IPSec between two Edgerouter X devices:
  • Local subnet: 192.168.1.0/24
  • Remote subnet: 192.168.2.0/24
  • Public endpoints: A your main site and B branch office
  • PSK: a strong random value

Site-to-site IPSec VPN Edgerouter X to Edgerouter X

• Prerequisites:
  • Both sites have static WAN IPs or reliable Dynamic DNS
  • Both routers have internet access and updated firmware
• Step-by-step outline:
  1. On Router A: define the remote peer Router B and the local networks to be tunneled.
  2. Create the IPSecProposal IKE and ESP parameters with matching encryption and hashing.
  3. Configure the ipsec site-to-site peer with peer IP, PSK or certificate, and Local/Remote Subnets.
  4. Set up firewall rules to allow VPN traffic and permit tunneled traffic.
  5. Add a static route on both sides to push remote subnets through the VPN tunnel.
  6. Bring the tunnel up and test connectivity ping across subnets.
• Practical tips:
  • Use a consistent VPN subnet e.g., 10.0.8.0/24 for the tunnel to prevent overlap with LANs.
  • If you see phase 1/2 failures, double-check PSK, IKE version v2 recommended, and NAT-T settings.
  • Enable dead peer detection DPD to quickly recover from outages.
• Verification:
  • Check VPN status on both routers; ensure tunnel shows as up
  • Ping from a host on Site A to a host on Site B across VPN
• Common pitfalls:
  • Subnet overlap causing routing issues
  • Firewall misconfigurations blocking IKE/ESP or ESP-transport traffic
  • MTU issues leading to dropped packets; adjust MSS/MTU if needed

Remote access IPSec VPN site-to-user

• Prerequisites:
  • One Edgerouter X with a public IP or DDNS
  • User accounts configured PSK or certificate-based
• Setup outline:
  1. Create a user profile or PSK for PSK-based auth or install a certificate for user authentication
  2. Define an IPSec tunnel for remote access, selecting the appropriate user pool or PSK
  3. Configure policies to allow client IPs to access internal subnets
  4. Set up firewall rules to permit VPN clients through the VPN interface
  5. Provide the VPN client with configuration details server address, pre-shared key or cert, and DNS settings

  2. Define a WireGuard interface wg0 on the Edgerouter X
  3. Add peers clients with their public keys and allowed IPs
  4. Configure allowed subnets and keep-alives
  5. Set firewall rules to permit UDP commonly 51820 traffic for WireGuard
  6. Establish routing so VPN clients can access internal networks
• Security tips:
  • Use a dedicated subnet for WireGuard peers e.g., 10.9.0.0/24
  • Rotate keys periodically and monitor for any unauthorized peers
• Troubleshooting:
  • If peers can’t connect, verify that port is open and forwarded if behind NAT
  • Check that the server’s WG interface is up and peers are properly configured

Firewall, NAT, and routing tips

• General approach:
  • Keep a clear separation between LAN and VPN subnets
  • Use minimal firewall rules necessary to reduce attack surface
  • Implement NAT where appropriate for outgoing traffic from VPN subnets
• Example rule ideas:
  • Allow established/related connections
  • Permit IKE, ESP, and NAT-T for IPSec
  • Allow OpenVPN UDP 1194 or your chosen port
  • Allow WireGuard UDP 51820
• Routing guidance:
  • Add static routes for VPN subnets pointing to the VPN interface
  • Ensure DNS resolution works for VPN clients either push internal DNS or use public DNS with split-horizon
• Monitoring:
  • Regularly check VPN tunnel status, interface counters, and system load
  • Enable logging for VPN events and firewall hits to troubleshoot faster

Common issues and fixes

• IPSec tunnel not coming up:
  • Check PSK or certificate trust, IKE Phase 1/2 parameters, and firewall ports
• Remote users cannot reach internal subnets:
  • Verify client IPs, correct route advertisements, and NAT rules
• OpenVPN performance is poor:
  • Consider tuning cipher and compression settings, or switch to WireGuard for better throughput
• WireGuard peer cannot connect:
  • Confirm public keys, allowed IPs, and firewall rules
• Dynamic IP on WAN:
  • Use Dynamic DNS and ensure OpenVPN/IPSec configurations reference the DDNS hostname when applicable

Optional: performance and monitoring tips

• CPU headroom:
  • Edgerouter X has limited CPU power; running multiple VPNs or heavy traffic can push the device toward its limits
  • If you see high CPU usage, consider staggering VPNs e.g., only one VPN type active at peak times
• QoS and traffic shaping:
  • Use simple QoS rules to ensure VPN control traffic gets priority
• Backups:
  • Regularly export and save your EdgeOS configurations; keep a separate backup for each VPN type
• Logging and alerts:
  • Enable syslog logging for VPN services and set up alerts if tunnels go down

Frequently Asked Questions

What is the difference between Site-to-Site IPSec and Remote Access IPSec on Edgerouter X?

Site-to-Site IPSec connects two networks over the internet, creating a secure tunnel between them. Remote Access IPSec lets individual users connect to your network from anywhere, effectively turning their devices into remote clients.

Can I run OpenVPN and WireGuard at the same time on the same Edgerouter X?

Yes, you can run multiple VPN solutions concurrently, but you’ll want to plan resources and firewall rules carefully to avoid conflicts and ensure performance remains acceptable.

Which VPN should I prefer for performance on Edgerouter X?

WireGuard generally offers the best performance on a device like the Edgerouter X due to its lightweight protocol. OpenVPN can be a good fallback for compatibility, while IPSec is common for site-to-site connections.

Do I need certificates for remote access IPSec?

Certificates provide better scalability and security than pre-shared keys, especially in larger deployments. They are recommended if you have many remote users.

How do I choose VPN subnets to avoid conflicts with my LAN?

Pick non-overlapping private subnets for VPNs, such as 10.10.10.0/24 for a site-to-site tunnel and 10.9.0.0/24 for WireGuard peers. Document all subnets so you don’t reuse them elsewhere.

Is it safe to expose OpenVPN or WireGuard ports to the internet?

Only expose what’s necessary and use strong authentication. Prefer VPN-only access from trusted IPs or implement multi-factor authentication where possible.

How often should I update the Edgerouter X firmware?

Keep firmware up to date with the latest stable release to benefit from security patches and performance improvements. Check release notes for VPN-related fixes.

How do I test a newly created VPN tunnel?

From a host on one side, try pinging a host on the other side’s VPN subnet. Verify routes and check the VPN status on both routers.

Can I use dynamic DNS for remote access VPN?

Yes, dynamic DNS is common for remote access VPNs, but you’ll need to ensure client configurations reference the dynamic hostname rather than a fixed IP.

What should I do if VPN packets are dropped?

Check MTU and MSS settings, ensure NAT-T is enabled if behind NAT, and verify that there are no conflicting firewall rules blocking VPN traffic.

Body

Why use Ubiquiti EdgeRouter X for VPN

• Compact, affordable hardware with solid routing performance for a home lab or small office.
• Flexible EdgeOS the EdgeRouter operating system lets you configure IPsec, OpenVPN, and WireGuard where supported without subscribing to a separate service.
• Strong firewall capabilities, NAT, and traffic shaping can help you isolate VPN traffic from your main LAN and prioritize remote access connections.
• Community and official docs are rich enough for DIY setups, with plenty of examples for site-to-site and remote access configurations.
• You can repurpose existing hardware, maintain control over your own tunnel endpoints, and avoid cloud-based single points of failure.

What to expect in terms of performance

• The EdgeRouter X’s CPU and hardware design are optimized for routing, not for high-end cryptography. When you enable VPN endpoints, you’ll see a drop in raw throughput compared to native routing.
• IPsec site-to-site can push hundreds of Mbps on good links if both ends are capable, but OpenVPN and WireGuard workloads may vary more with CPU and encryption settings.
• Plan for a modest headroom buffer: if you’re linking multiple sites or handling heavy remote-access traffic, you may want to consider a more powerful EdgeRouter model or dedicated VPN hardware in the future.

VPN options on EdgeRouter X

IPsec Site-to-Site recommended for branch-to-branch or office-to-office

• Best for permanent tunnels between two networks, low overhead, good compatibility with most enterprise-grade equipment.
• Works well for linking remote offices, backups, and centralizing security policies.
• Can be configured to auto-reconnect, with dead-peer detection DPD and perfect forward secrecy PFS settings.

Key considerations

• You’ll need to coordinate SPIs, pre-shared secrets or certificates, andIKE/ESP policies with the peer device.
• Ensure your firewall rules allow the IPsec traffic typically ESP, AH, and UDP 4500 for NAT-T. exact ports depend on your peers.

Practical tips

• Use a strong pre-shared secret or move to a certificate-based setup for stronger authentication.
• Lock down which subnets are allowed to traverse the tunnel to reduce exposure.
• Test reversals by simulating failover and verifying re-key and reconnect behavior.

OpenVPN Server Remote Access

• Great for allowing multiple clients laptops, phones to securely connect to your home network.

• Simpler to manage for small teams. you can generate client profiles and revoke them if needed. Microsoft edge vpn: ultimate guide to using VPNs with Edge on Windows, extensions, and privacy 2026

• Performance depends on CPU and encryption parameters. WireGuard can offer better throughput where supported.

• OpenVPN server setup on EdgeRouter X uses standard OpenVPN concepts: server config, client config, and TLS/PKI if you choose certificate-based auth.

• You’ll typically deploy a tunnel network for example, 10.8.0.0/24 and push routes to clients.

• Use TLS-auth or a static key for extra security if you’re not ready for full PKI.

• Push DNS or split-tunnel rules to control which traffic goes through the VPN. Turn off microsoft edge vpn 2026

• Create client export profiles that are easy for users to install on their devices.

WireGuard where supported

• WireGuard is a lean, modern VPN that often outperforms OpenVPN in throughput and latency.

• Support on EdgeRouter X depends on your firmware. it’s becoming more common in newer EdgeOS releases, sometimes as an experimental or add-on feature.

• Simpler key management and fewer moving parts than IPsec/OpenVPN.

• If your firmware supports WireGuard, set up a dedicated interface e.g., wg0, assign internal VPN addresses, and configure peers with allowed IPs. Expressvpn browser extension edge: complete guide to installation, features, performance, and safety on Microsoft Edge 2026

• Monitor CPU usage during VPN traffic. WireGuard tends to be lighter on resources than OpenVPN.

• Keep firmware updated to get the newest WireGuard improvements and bug fixes.

Getting started: prerequisites and planning

• EdgeRouter X with the latest EdgeOS firmware check the official support page for your model and firmware version.
• A static public IP or a reliable dynamic DNS setup for remote access.
• A clear idea of your LAN subnets and VPN subnets to avoid overlap e.g., 192.168.1.0/24 for LAN, 10.8.0.0/24 or 10.9.0.0/24 for VPN networks.
• For IPsec: decide on pre-shared secret vs certificate-based authentication and which subnets will be encrypted.
• For OpenVPN: decide on server mode remote access and how many client profiles you’ll need.
• Access to the EdgeRouter X GUI https://192.168.1.1 or SSH, plus admin credentials.

Secure remote access basics

• Use strong admin credentials and consider disabling the default admin account or limiting admin access to a management VLAN.
• Enable two-factor authentication if your EdgeOS version supports it for remote management.
• Keep firewall rules strict and minimize unnecessary open ports.

Step-by-step: setting up IPsec site-to-site

Note: exact CLI syntax can vary by EdgeOS version. The steps below outline a solid workflow you can adapt to your firmware, with GUI shortcuts when available.

1. Prepare the peers

• Collect: peer public IP, LAN subnets, VPN subnet for tunnel, and authentication method PSK vs certificates.

2. Enable the IPsec interface for traffic

• GUI: EdgeRouter > VPN > IPsec > Enable IPsec traffic on the primary WAN interface e.g., eth0.
• CLI: set vpn ipsec ipsec-interfaces interface eth0

3. Define the IPsec peer

• GUI: Add peer, specify remote peer IP, select authentication, provide pre-shared key or certificate info, and choose the ike/group IKEv2 is preferred if available.
• CLI: set vpn ipsec site-to-site peer authentication mode pre-shared-secret
  set vpn ipsec site-to-site peer authentication pre-shared-secret ‘‘
  set vpn ipsec site-to-site peer ike-group IIKE
  set vpn ipsec site-to-site peer default-esp-group ESP-3DES-AES use a modern ESP group, e.g., AES256

4. Define local/remote networks

• GUI: specify local network your LAN and remote network peer’s LAN for traffic to be encrypted.
• CLI: set vpn ipsec site-to-site peer tunnel 192.168.1.0/24 10.10.0.0/24

5. Configure a firewall rule to allow VPN traffic

• GUI: create a rule to allow IPsec ESP/UDP 500/4500 and the tunnel networks.
• CLI: set firewall name VPN-IN default-action drop. set firewall name VPN-IN rule 10 action accept. set vpn ipsec policy exchange

6. NAT and routing

• GUI: ensure NAT exemption policy-based routing is in place so VPN traffic to the remote network isn’t NAT’d incorrectly.
• CLI: set nat source rule 100 outbound-interface eth0. set nat source rule 100 source address 10.8.0.0/24. set nat source rule 100 translation address masquerade

7. Test

• Try pinging a host on the remote network from a client behind your ER-X and watch the tunnel status in the GUI or with show vpn sessiondb.

If your peers use certificates or advanced IKE settings, adjust accordingly. Always test by bringing down the link and verifying reestablishment works automatically. F5 big ip edge vpn client download mac complete macOS guide for download, install, configure, troubleshoot, and optimize 2026

Step-by-step: OpenVPN Server Remote Access

1. Prepare the VPN server

• Ensure OpenVPN server packages are supported by your EdgeOS version.

2. Configure the OpenVPN server

• GUI: EdgeRouter > VPN > OpenVPN > Server. Choose UDP, set port 1194 typical, set tunnel network e.g., 10.8.0.0/24, and define client-access rules.
• CLI: set vpn openvpn server server1 mode ‘server’ or equivalent for your firmware

3. TLS and client authentication

• Use TLS-auth or TLS-crypt, generate a CA and client certificates or use static keys if you’re simpler.

4. User management

• GUI: add client credentials or upload a .ovpn profile.
• CLI: create a local user if your firmware uses local accounts for OpenVPN clients

5. DNS and routing

• Push DNS to clients if you want to keep name resolution within your network.

6. Firewall and NAT

• Allow VPN clients to reach your LAN while preventing unnecessary exposure.

7. Client testing

• Import the .ovpn profile on a device laptop, phone and connect. Verify you can access internal resources and reach the Internet via VPN if that’s your goal.

MacOS/iOS/Android OpenVPN clients will need the .ovpn profile. Windows users often rely on the OpenVPN Connect client. You can distribute profiles securely and revoke them if needed.

Step-by-step: WireGuard if your firmware supports it

1. Enable and configure

• GUI or CLI: create a wg0 interface, assign an internal VPN address e.g., 10.9.0.1/24, and configure peers with their public keys and allowed IPs.

2. Peer configuration

• Add the allowed IPs that should go through the tunnel e.g., 10.9.0.0/24, 0.0.0.0/0 for full-tunnel depending on your needs.

3. Firewall and NAT

• Ensure traffic from wg0 is allowed to reach LAN and that NAT rules are consistent with how you want clients to access the Internet.

4. Client setup

• Generate client keys and configuration, typically including a private key, public key, and endpoint information.

5. Testing

• Connect a client and verify that the expected traffic routes through the VPN.

Note: WireGuard on EdgeRouter X depends on firmware support. If not available, you can still run IPsec or OpenVPN effectively.

Security tips and best practices

• Keep firmware up to date: security patches and VPN improvements come with newer EdgeOS releases.
• Use strong authentication: prefer certificate-based auth for IPsec or TLS-based OpenVPN with TLS-auth/TLS-crypt.
• Separate management and VPN networks: place admin interfaces on a dedicated management VLAN, and keep VPN networks on separate subnets.
• Enable logging and monitoring: regularly check VPN session status, failed auth attempts, and tunnel stability.
• Regularly audit firewall rules: remove obsolete rules, verify NAT exceptions, and ensure you’re not exposing sensitive internal services.
• Lock down remote access: limit admin access to VPN users, restrict IPs, and apply two-factor authentication where supported.
• Back up configurations: create and store a backup of your EdgeRouter X config before major changes.
• Plan for redundancy: if VPNs are critical, consider a second device or a secondary WAN link for failover.

Performance considerations and limitations

• VPNs consume CPU cycles, so expect some drop in throughput when VPNs are enabled.
• IPsec generally has steady performance, but heavy cryptography on OpenVPN especially with TLS can be more demanding.
• WireGuard, if supported, tends to offer higher throughput and lower latency compared to OpenVPN on the same hardware.
• For a home or small office, you’ll typically see VPN throughput that’s well below the theoretical gigabit speeds of the Ethernet links. plan for 100 Mbps to a few hundred Mbps in real-world use, depending on encryption and device load.
• If you’re scaling to multiple sites or many clients, you may want to upgrade to a more powerful EdgeRouter model or distribute VPN duties across dedicated devices.

Troubleshooting common VPN issues

• VPN tunnel won’t establish:
  • Check IPsec/IKE policies on both ends. ensure NAT-T is enabled if behind NAT.
  • Verify that the correct pre-shared secret or certificates are in use.
  • Confirm firewall rules allow VPN traffic ESP, UDP 500/4500 for IPsec. UDP 1194 for OpenVPN.
• Slow VPN speeds:
  • Verify CPU load on the EdgeRouter X during VPN traffic.
  • Consider enabling WireGuard where possible, or tune OpenVPN to lighter ciphers.
• Clients can’t reach internal resources:
  • Confirm route advertisements for the VPN subnet.
  • Check DNS settings pushed to clients.
  • Ensure firewall rules permit traffic from VPN subnets to internal networks.
• VPN disconnects and reconnects:
  • Check DPD and IKE rekey timing. adjust keepalive and rekey intervals if needed.
  • Ensure internet connectivity is stable on the router and client devices.
• Dynamic DNS issues:
  • Confirm your DDNS provider is correctly configured and the ER-X is updating the hostname as expected.
  • Ensure firewall rules don’t block DNS updates.

Monitoring and maintenance

• Regularly review VPN session logs and interface statistics through EdgeOS GUI or CLI.
• Set up alerts for VPN downtime if your monitoring stack supports it.
• Periodically rotate pre-shared secrets or re-check certificate validity for IPsec or OpenVPN environments.
• Document your VPN topology: keep a simple diagram with IP ranges, peers, and tunnel purposes for quicker future changes.

Best practices for home and small offices

• Start with IPsec site-to-site for a permanent connection between your home network and a trusted remote site e.g., a coworker’s lab or a remote office.
• Add OpenVPN remote access for individuals who need to connect from outside.
• If you can, test WireGuard on firmware that supports it to see if you can gain performance improvements.
• Keep the ER-X in a dedicated network segment for VPN devices to minimize accidental exposure.
