Understanding EdgeRouter VPN options

Before you dive into commands, here’s a quick map of the main VPN options on EdgeRouter:

OpenVPN: Client and server modes are supported. Strong for remote-access use. Typically runs over UDP 1194 default but can be changed.
IPsec: Strong, scalable for site-to-site and remote access. Uses IKEv1 or IKEv2 depending on implementation. Common ports: 500, 4500, and ESP.
L2TP: Often paired with IPsec for encryption. Easier to set up on the client side, but less flexible and sometimes blocked by networks.
Site-to-site vs client-to-site: Site-to-site connects two networks directly; client-to-site lets individual devices connect to a central network.

Note: For EdgeRouter, you’ll often end up using strongSwan for IPsec and OpenVPN software packages, plus built-in firewall/NAT rules.

Prerequisites and planning

EdgeRouter model and firmware: Ensure you’re on a recent EdgeOS/EdgeRouter firmware. Check for updates.
Public IP or dynamic DNS: If your edge device sits behind a NAT or changing IP, consider a DDNS service.
Certificates and keys: For IPsec and OpenVPN, you’ll typically need CA certs, server certs, and client certs. For OpenVPN, you can also use static keys.
Network plan:
- Internal subnets for each side e.g., 192.168.1.0/24 and 192.168.2.0/24.
- Which networks should be reachable over VPN.
- Which services should be allowed through the VPN DNS, NTP, etc..
Firewall and NAT: Decide which traffic should be allowed, and whether to NAT VPN traffic to the LAN or public internet.

OpenVPN on EdgeRouter server and client configuration

OpenVPN is a popular choice for remote access. Here’s a concise setup flow.

1 Prepare certificates simplified

Create a CA, server certificate, and client certificate. You can use easy-rsa or a similar tool on a separate host, then copy the resulting .ovpn file for clients.
Alternatively, you can use a static key taffer for simple setups, but a full PKI is more scalable.

2 Install and enable OpenVPN service

On EdgeRouter, you’ll enable VPN via the GUI or CLI, typical steps:
- Create a VPN server instance for OpenVPN.
- Upload or place the server certificate and key, CA certificate, and DH parameters if using TLS.
- Configure server mode tun or tap, port default 1194, protocol UDP recommended.

3 Configure routing and firewall

Add firewall rules to allow VPN traffic UDP 1194 to the VPN server.
Route VPN clients’ IP range to the internal networks.
If you want Internet traffic through VPN, enable redirect-gateway and set DNS accordingly.

4 Client configuration

Generate client config .ovpn that includes the CA, client cert, and key, or provide a separate client certificate and key with the CA chain.
Example client config elements:
- dev tun
- proto udp
- remote your-edge-router-public-ip 1194
- resolv-retry infinite
- nobind
- persist-key
- persist-tun
- ca ca.crt
- cert client.crt
- key client.key
- tls-auth ta.key 1 if using TLS auth
- cipher AES-256-CBC
- comp-lzo
- verb 3

5 Testing OpenVPN

Start the OpenVPN server on EdgeRouter.
Use a client to connect and verify IP, internal network reachability, and DNS resolution.

Tips for OpenVPN on EdgeRouter

Use a stable port and protocol; UDP tends to be faster, but TCP can help in restrictive networks.
Keep the server and client config minimal to reduce error space.
Enable logging on both sides to capture connection attempts and errors.
If you’re behind double NAT or CGNAT, you may need port-forwarding or a public-facing DNS.

IPsec VPN on EdgeRouter site-to-site and remote access

IPsec is a robust choice for both site-to-site and client connections.

1 Site-to-site IPsec two-edge-router tunnels

Define the network topology: LAN subnets on both ends.
Create IKEv2 or IKEv1 proposals encryption, hash, DH group.
Create phase 1 IKE and phase 2 IPsec policies.
Define the tunnel endpoints with public IPs.
Set the traffic selectors interesting traffic to match internal subnets.
Add firewall rules to allow IPsec traffic and the inner IPsec ESP traffic.
Test using ping across sites and verify the tunnel status.

2 Remote access IPsec IKEv2

Create a user authentication method PSK or certificate-based for clients.
Define a pool/virtual IP range for VPN clients.
Configure client authentication and DNS push as needed.
Ensure the firewall allows UDP 500/4500 and ESP.

3 Practical considerations

NAT traversal NAT-T support: essential if you’re behind NATs.
Dead Peer Detection DPD: helps keep tunnels alive.
Perfect Forward Secrecy PFS: choose a DH group for extra security.
Certificate-based auth vs PSK: certificate-based is more scalable for many clients.

IPsec configuration snippets conceptual

IKEv2 proposals: aes256-sha256-modp1024
ESP proposals: aes256-sha256
DH group: modp2048
PSK: a strong passphrase

Troubleshooting IPsec

Check IPSec status: look for SAs up, peers established.
Verify phase 1 and phase 2 negotiation with logs.
Confirm that firewall rules allow the IPsec-related ports and protocols.
Confirm that the remote end matches the same proposals and lifetimes.

L2TP over IPsec for client connections

L2TP over IPsec is a traditional method for client VPNs. How to turn off vpn on microsoft edge: disable extension, disconnect Windows VPN, and turn off Edge Secure Network 2026

2 Client setup

On Windows/macOS/iOS/Android, configure L2TP over IPsec with the server’s public IP, PSK, and assigned username/password.
Verify connectivity and split tunneling settings if needed.

3 Security and reliability

PSK should be strong; certificate-based L2TP is more secure but harder to manage.
Consider requiring MFA for VPN access if possible.
Monitor logs for failed logins and IP leaks.

Firewall and routing best practices

Default deny: allow only necessary VPN traffic OpenVPN UDP 1194, IPsec ports 500/4500, ESP, 1701 for L2TP.
NAT rules: decide whether VPN clients’ traffic should be NATed on the EdgeRouter when they exit to the internet.
DNS handling: push internal DNS servers to VPN clients if you need internal name resolution.
Split tunneling: decide if only internal resources should go through VPN or all traffic.

High-level comparison: OpenVPN vs IPsec vs L2TP

OpenVPN
- Pros: Flexible, easy to push client configs, works behind NAT, strong community support.
- Cons: Sometimes slower on mobile networks, may require extra certificates.
IPsec
