What makes Ubiquiti EdgeRouter a solid VPN choice
- EdgeRouter devices run EdgeOS, which blends easy-to-use Web UI with a powerful CLI. For many home labs and small offices, this means you can implement robust VPNs without buying a dedicated firewall appliance.
- Native IPsec support is a strong point. It’s well suited for site-to-site links and for remote-access scenarios when you pair IPsec with L2TP for clients.
- Hardware variety matters: EdgeRouter X more affordable vs EdgeRouter 4/6/8 or higher-end models. Higher-end devices deliver more CPU headroom for VPN throughput and multiple tunnels, which matters if you’re linking two sites or distributing VPNed clients across many users.
VPN types you’ll likely use with EdgeRouter
- IPsec Site-to-Site: The most common choice for connecting two networks securely over the internet. Great for linking locations, branches, or cloud networks to your on-prem network.
- L2TP over IPsec Remote Access: Useful for individual devices that need to connect back to your home/office network. This is typically simpler to configure on client devices while being secured by IPsec.
- OpenVPN: Not officially built into EdgeRouter as a native server option in all EdgeOS versions, and setting it up can be more involved. If you need OpenVPN specifically, you’ll typically run it on a separate device or VM and route traffic as needed. Some users experiment with community packages or alternate setups, but IPsec remains the mainstream approach on EdgeRouter.
Choosing the right VPN type for your EdgeRouter setup
- Small to medium sites with two networks: IPsec Site-to-Site is usually best. It’s fast on supported hardware, secure, and stable.
- Remote workers needing occasional access: L2TP over IPsec remote access is simple to deploy for Windows/macOS/iOS/Android clients.
- If you must use a VPN provider for client traffic e.g., when you want all traffic to go through a provider like NordVPN for privacy on all devices behind EdgeRouter: know that EdgeOS doesn’t natively run most consumer VPN client apps. You can either run the VPN on a separate device behind the EdgeRouter, or set up site-to-site with a corporate VPN gateway if your provider supports IPsec/IKEv2 site-to-site, or route individual devices to the VPN client directly.
A practical IPsec Site-to-Site setup step-by-step example
Note: The exact CLI syntax can vary by EdgeOS version. Always back up your config before applying changes, and test changes during a maintenance window if possible.
Prerequisites
- Two EdgeRouter devices or one EdgeRouter and one remote gateway with Internet access and a reachable public IP for each side.
- A shared pre-shared key PSK for IPsec authentication.
- Private networks clearly defined e.g., Local: 192.168.1.0/24 on Site A, Remote: 192.168.2.0/24 on Site B.
- Basic firewall rules allowing IPsec traffic UDP 500, UDP 4500 for NAT-T, and ESP protocol 50.
Step-by-step CLI
- Enter configuration mode
- configure
- Define IKE IKEv2 is preferred for newer devices
- set vpn ipsec ike-group IKE-GROUP proposal 1 encryption aes128
- set vpn ipsec ike-group IKE-GROUP proposal 1 hash sha256
- set vpn ipsec ike-group IKE-GROUP proposal 1 dh-group 14
- set vpn ipsec ike-group IKE-GROUP lifetime 3600
- Define IPsec ESP the actual data path
- set vpn ipsec esp-group ESP-GROUP proposal 1 encryption aes128
- set vpn ipsec esp-group ESP-GROUP proposal 1 hash sha256
- set vpn ipsec esp-group ESP-GROUP lifetime 3600
- Configure the IPsec options
- set vpn ipsec options enable-no-pfs no
- set vpn ipsec options keep-alive enable
- Configure the local and remote endpoints
- set vpn ipsec site-to-site peer authentication mode pre-shared-secret
- set vpn ipsec site-to-site peer authentication pre-shared-secret 'yourPSK'
- set vpn ipsec site-to-site peer ike-group IKE-GROUP
- set vpn ipsec site-to-site peer default-profile 'VPN-DEFAULT'
- set vpn ipsec site-to-site peer local-address
- set vpn ipsec site-to-site peer tunnel 1 local-prefix 192.168.1.0/24
- set vpn ipsec site-to-site peer tunnel 1 remote-prefix 192.168.2.0/24
- Define the security profiles
- set vpn ipsec ipsec-interfaces interface ppp0? use the right interface. for EdgeRouter typically eth0 or eth1
- set vpn ipsec site-to-site peer tunnel 1 crypto-profile ESP-GROUP
- Commit and save
- commit
- save
- Exit
- exit
If you’re working with a specific EdgeRouter model or EdgeOS version, check the official EdgeRouter documentation for exact syntax. The general flow, however, remains the same: define IKE and ESP parameters, specify peers and local/remote networks, and apply the tunnel with a PSK.
Configuring L2TP/IPsec remote access for clients step-by-step
- L2TP over IPsec gives your individual devices client VPN access with a familiar setup.
- Prerequisites
- A pool of IPs for VPN clients e.g., 192.168.3.0/24
- A pre-shared key for IPsec P-RESHARED KEY and user accounts
- Example CLI steps simplified
- set vpn l2tp remote-access authentication mode local
- set vpn l2tp remote-access authentication local-users username USERNAME password PASSWORD
- set vpn l2tp remote-access ipsec-settings ike-version 2
- set vpn l2tp remote-access ipsec-settings pre-shared-key "presharedkey"
- set vpn l2tp remote-access ipsec-settings encryption aes128
- set vpn l2tp remote-access ipsec-settings integrity sha256
- set vpn l2tp remote-access ipsec-settings dh-group 14
- set vpn l2tp remote-access shared-secret 'sharedsecret'
- set vpn l2tp remote-access enable
- set vpn l2tp remote-access local-ip 192.168.1.1
- set vpn l2tp remote-access client-ip-pool start 192.168.3.2
- set vpn l2tp remote-access client-ip-pool stop 192.168.3.254
- Routing and firewall
- Ensure VPN clients can reach your internal subnets
- Allow IPsec UDP 500, UDP 4500 and ESP protocol 50 through firewall
- Add NAT exceptions so VPN clients aren’t double-NAT’ed when accessing the internal network
- Client setup
- Windows/macOS/iOS/Android clients use L2TP with the PSK and the local user credentials
- Confirm you can ping internal resources from the VPN client
Common pitfalls and how to avoid them
- NAT traversal and firewall blocks: If you’re behind double-NAT or a strict firewall, UDP 500/4500 and ESP may get blocked. Use NAT-T and verify port access with a quick external port test.
- Dynamic IP on the edge: If the edge gateway’s public IP changes, use a Dynamic DNS service to keep a stable hostname for your IPsec tunnel endpoint.
- Incorrect local/remote prefixes: Mismatched subnets are a top cause of failed tunnels. Double-check both sides’ local and remote LAN prefixes.
- MTU issues: VPN tunnels can introduce fragmentation. If you see intermittent connectivity or dropped packets, adjust MTU to a smaller value on both ends.
- Performance limits: EdgeRouter models have different VPN throughput ceilings. If you’re seeing slow VPN performance, consider upgrading to a higher-end model or reduce tunnel count.
Routing, NAT, and DNS considerations for VPNs
- For site-to-site: Route traffic for the remote network through the tunnel. Ensure the remote network’s subnets are correctly defined on both sides.
- For remote access: Use a dedicated VPN client subnet and route client traffic to internal resources as needed. If you want VPN clients to access the internet through the VPN, you’ll need appropriate routing and firewall rules to split tunnel or force all traffic through the VPN.
- DNS behavior: Decide if VPN clients should use internal DNS servers for internal resource resolution or public DNS. You may push internal DNS server settings to remote clients to improve name resolution reliability.
Dynamic IPs, DNS, and remote access testing
- Dynamic IPs: If your EdgeRouter’s WAN IP changes, set up a DDNS service No-IP, DynDNS, etc. and update your IPsec remote peers accordingly or use a remote-access method that tolerates changing endpoints.
- DNS: If you’re hosting internal services like a file server or printer behind EdgeRouter, ensure VPN clients can resolve those hosts using a suitable DNS server or hosts file.
- Testing: After configuring VPNs, test connectivity in this order:
1 Ping devices across the tunnel 192.168.1.x <-> 192.168.2.x.
2 Test access to resources behind each site file shares, printers, internal apps.
3 Test VPN client connections for remote access from multiple devices and networks.
4 Verify behavior when a remote client disconnects and reconnects.
Performance considerations and real-world expectations
- CPU and throughput: EdgeRouter models with stronger CPUs will sustain higher VPN throughput. Expect higher throughput on IPsec sites than on mixed traffic VPNs if you’re using multiple tunnels.
- Encryption and hash choices: AES-256 with SHA-256 offers strong security but can add CPU overhead. AES-128 with SHA-256 is a common compromise.
- Tunnel count: Each site-to-site tunnel and remote-access user adds load. Plan for growth by provisioning headroom in your EdgeRouter model.
- Power and heat: VPN operations can push the CPU. Ensure adequate cooling and stable power to avoid throttling.
Security best practices you should follow
- Use strong pre-shared keys PSKs and unique keys per VPN peer.
- Prefer IKEv2 with AES-256 and SHA-256 for reliability and security.
- Keep EdgeOS firmware up to date to benefit from security fixes and improvements.
- Limit VPN access to only the resources that are necessary. Implement least-privilege firewall rules.
- Regularly back up your VPN configurations and test restores.
- Consider using a dedicated VPN gateway for high-security use cases if needed.
Maintenance, backups, and troubleshooting tips
- Backups: Regularly export and save EdgeRouter config backups. Keep a copy offline.
- Logs: Review VPN-related logs for errors IKE negotiation failures, authentication failures, or tunnel drops.
- Timeouts: If tunnels drop periodically, consider rekey settings, keepalives, and dead-peer detection adjustments.
- Firmware: Only upgrade after testing in a controlled environment, especially if you rely on a very specific VPN setup that might be affected by changes.
Is NordVPN a good fit with EdgeRouter?
- NordVPN can secure client devices behind EdgeRouter by joining those devices to the VPN provider individually e.g., a laptop or phone connected to the network behind EdgeRouter. Edgerouters do not natively run the NordVPN app as a VPN client for all traffic on the edge itself. If you want all traffic from devices behind the EdgeRouter to route through NordVPN, you’ll typically configure VPN on a separate device or consider a VPN-capable router behind EdgeRouter, or use a provider that supports IPsec site-to-site for the enterprise-style gateway approach. For most EdgeRouter users, IPsec Site-to-Site and L2TP/IPsec remote access cover the vast majority of practical use cases. If you’re exploring NordVPN, the banner above is a handy starting point for potential savings while you manage VPN traffic with EdgeRouter.
Frequently Asked Questions
What is an EdgeRouter and why would I use VPN on it?
EdgeRouter devices run EdgeOS, giving you professional-grade routing with VPN support. VPNs on EdgeRouter help you securely connect two networks, or give remote users secure access to a private network without relying on a separate VPN appliance.
Can EdgeRouter host an OpenVPN server?
EdgeRouter does not always offer a native OpenVPN server in every EdgeOS version. Some users explore workarounds or run OpenVPN on a separate device. If you need OpenVPN specifically, plan to host it on another device and route traffic accordingly.
Can I use WireGuard on EdgeRouter?
WireGuard isn’t natively included in EdgeRouter’s core package in all versions. Some users experiment with third-party packages, but it isn’t officially supported by Ubiquiti. If you want WireGuard support, you may need to run it on a separate gateway device or look for community-driven projects with caution.
Do I need a static IP to use IPsec site-to-site on EdgeRouter?
A static IP simplifies site-to-site VPN configuration and stability, but it’s not strictly required. If your public IP changes, you can use DDNS on one or both sides and update the remote peer as needed.
How do I test if my VPN tunnel is up?
Check VPN status in the EdgeRouter’s UI or CLI, run a ping across the tunnel from a host on Site A to a host on Site B, and verify that the remote networks are reachable and traffic paths are correct.
Can I route all my traffic through a VPN on EdgeRouter?
Yes, you can set up a full-tunnel or split-tunnel configuration, depending on your goals. Full-tunnel routes all client traffic including internet-bound through the VPN, while split-tunnel sends only specific traffic through the VPN.
How do I secure my VPN on EdgeRouter?
Use strong IKE/ESP proposals AES-256, SHA-256, strong DH groups, enforce PSKs, keep firmware up to date, and restrict firewall rules to the minimum necessary. Regular backups are essential.
What models should I buy for better VPN performance?
Higher-end EdgeRouter models with faster CPUs e.g., EdgeRouter 6P or equivalent deliver better VPN throughput, especially with multiple tunnels. If you’re running multiple remote sites or dozens of remote clients, headroom matters.
How do dynamic IPs affect VPN on EdgeRouter?
Dynamic IPs can complicate site-to-site VPNs. Use a DDNS service for endpoints and ensure you have a plan to update remote peers when IPs change. Remote-access VPNs with L2TP/IPsec can be less affected but testing is still important.
Is it safe to combine EdgeRouter VPNs with consumer VPN providers like NordVPN?
For site-to-site VPNs, you typically don’t replace IPsec with consumer provider VPNs. For client devices, you can connect to consumer VPNs on individual devices behind EdgeRouter, or route through a separate VPN-enabled gateway if your policy requires it. Always align with your security and privacy requirements.
If you’re looking to optimize your Ubiquiti EdgeRouter VPN setup, the key is to start with a clear plan:
- Decide between IPsec site-to-site or L2TP/IPsec remote access based on your network topology.
- Select the EdgeRouter model that provides enough CPU headroom for your tunnel count and throughput needs.
- Use strong, tested crypto settings and keep firmware up to date.
- Plan for dynamic IPs with a DDNS solution if you don’t have a static IP.
- Keep a solid backup process for your VPN configuration.
With these pieces in place, you’ll have a resilient, secure VPN setup on EdgeRouter that serves both site-to-site connections and remote access for your users.
