VPN options you can configure with EdgeRouter GUI

IPsec Site-to-Site VPN strongSwan for connecting two networks as a private tunnel
IPsec Remote Access VPN for individual clients L2TP over IPsec
Basic firewall rules to protect VPN traffic and exclude VPN traffic from NAT when needed
Optional: split-tunnel vs. full-tunnel configurations depending on your goals

Note: EdgeRouter GUI doesn’t natively offer OpenVPN as a built-in option in many firmware versions. most users rely on IPsec-based solutions Site-to-Site and L2TP over IPsec for remote access. If you need OpenVPN specifically, you’ll typically run it on a separate device or explore alternative firmware on certain EdgeRouter models, but IPsec remains the most robust, widely supported option in EdgeOS for most users.

Prerequisites: what you should have ready before you start

EdgeRouter device ER-4 series, ER-6, or similar with the latest EdgeOS firmware or a recent stable release
A public IP address on the EdgeRouter or a reliable dynamic DNS setup
Remote peer public IP or hostname for site-to-site VPN
Shared secret PSK or certificate setup for IPsec, depending on your chosen method
Subnet plans for both your local LAN and the remote networks
Administrative access to the EdgeRouter GUI username and password
Basic firewall rules in place and an idea of which networks you want to allow VPN traffic to reach

Tip: Having a clean subnet plan ahead of time makes the GUI configuration much smoother and reduces the chance of address conflicts across sites.

Step-by-step: IPsec site-to-site VPN setup via the GUI

Access the EdgeRouter GUI

Open a browser and go to https:// and log in with your admin credentials.

Navigate to the VPN configuration area

In the GUI, find the VPN section often under the “VPN” tab or a dedicated “IPSec” section. You’ll set up a tunnel, pre-shared key, and the IKE settings here.

Create a new IPsec tunnel

Click “Add Tunnel” or “Add” under IPsec.
Give the tunnel a meaningful name for example, “SiteA-SiteB_IPsec”.
Enter the remote peer’s public IP address and the local/public IP if the EdgeRouter has multiple interfaces, select the correct one as the local endpoint.

Set authentication and encryption parameters

Choose an authentication method pre-shared key is the simplest for most setups.
Enter the PSK make it strong and unique, and keep a copy for the remote site.
Configure Phase 1 IKE and Phase 2 IPsec proposals: you’ll typically select matching settings on both sides e.g., IKEv2 or IKEv1, the same encryption like AES-256, Hash SHA-256, and perfect forward secrecy PFS group.
Define the local and remote networks for the tunnel’s traffic selectors Left/Right networks so only the intended subnets traverse the VPN.

Add a security policy and NAT rules

Create a firewall rule to allow IPsec protocol ESP and UDP ports 500 and 4500 if you’re using NAT-T.
Add a NAT exemption so VPN traffic isn’t mangled by NAT on the local network. Example: source your LAN subnet to the remote subnet.

Apply and test the tunnel

Save the configuration and apply.
Check the status indicators in the VPN section. if the tunnel doesn’t come up, review the PSK, remote IP, and tunnel selectors.
Use ping or traceroute from a host on the local network to a host on the remote network to confirm connectivity. If you’re not seeing the IPsec SA Security Association established, re-check Phase 1 and Phase 2 negotiation.

Fine-tune and secure

Ensure you’ve restricted management access to the EdgeRouter so only trusted devices can change the VPN.
Add logging or monitor VPN events to catch drops or renegotiations early.
If you experience intermittent drops, consider enabling dead peer detection DPD or adjusting rekey intervals to match the remote end.

Step-by-step: L2TP over IPsec remote access VPN setup via the GUI

Prepare EdgeRouter for L2TP/IPsec remote access

Confirm your firmware supports L2TP over IPsec in the VPN section. If not, you may need to enable an alternative remote access method or update firmware.

Enable L2TP server and IPsec settings

In the GUI, enable L2TP server functionality and configure IPsec with a strong pre-shared key.
Set up DNS for clients optional and define the local networks that remote clients should access.

Create user accounts for remote clients

Add user accounts with username and password or certificate-based authentication, depending on the EdgeRouter capabilities.

Configure remote access policies

Define which subnets can be reached by remote clients and adjust firewall rules accordingly.
Ensure the VPN client pool IP range doesn’t overlap with your LAN to avoid routing headaches.

Apply, test, and troubleshoot

Save settings and apply changes.
On a client device, configure a VPN connection using L2TP over IPsec with the EdgeRouter’s public IP and the PSK.
Verify connectivity to LAN resources and test both inbound and outbound traffic to confirm proper routing.

Hardening and best practices

Consider two-factor or hardware-backed authentication if your EdgeRouter and environment support it.
Regularly rotate the PSK and monitor login attempts.

Security, performance, and maintenance best practices

Use strong encryption and secure PSKs. avoid outdated ciphers.
Keep EdgeRouter firmware up to date to patch security vulnerabilities and improve compatibility with modern VPN clients.
Limit GUI access to a trusted management network or VPN themselves. disable unneeded services SSH, HTTP from exposed interfaces when possible.
Consider splitting VPN traffic if you don’t want all traffic to go through the VPN tunnel split tunneling.
Regularly audit firewall rules to ensure only necessary ports are open for VPN traffic.
Maintain a documented subnet plan and keep a current inventory of tunnel configurations, PSKs, and remote peers.

Common pitfalls and troubleshooting tips

Mismatched Phase 1/Phase 2 settings: Double-check the exact algorithms, hash, group, and lifetime values on both ends. mismatches are the leading cause of tunnel failure.
Incorrect remote network definitions: Ensure the local and remote LAN IP range definitions don’t overlap. an overlap causes traffic to be misrouted or dropped.
PSK errors: Very common. copy-and-paste PSK to avoid typos, and verify there are no extra spaces.
Firewall and NAT rules: If the tunnel is up but traffic can’t reach the remote network, re-check firewall rules and NAT exemptions.
Dynamic IP issues: If the remote site uses a dynamic IP, ensure you’re using a dynamic DNS service or a dynamic update mechanism. otherwise, the peer will fail to locate your EdgeRouter.
MTU and fragmentation: VPN tunnels can drop large packets. if you notice performance or reliability issues, reduce MTU on VPN interfaces or enable MSS clamping on relevant interfaces.
Client-side issues: If a client can connect but can’t reach internal resources, check split-tunnel vs. full-tunnel settings, client DNS, and the edge firewall rules.

Real-world use cases: when to pick site-to-site vs remote access

Small office connecting to a remote branch: IPsec site-to-site is often the cleanest solution, with a dedicated tunnel per site pair.
Remote workers who travel or work from home: L2TP over IPsec remote access is a practical choice, letting individuals connect securely from multiple locations.
Mixed environments: You might run IPsec site-to-site for the core branches and L2TP/IPsec for roaming workers or contractors.

Performance considerations and monitoring

VPN encryption does add CPU overhead. If your EdgeRouter is a smaller model, keep encryption settings appropriate for your hardware, and consider offloading heavy tasks to a more capable device if you consistently hit CPU limits.
Enable logging and periodic status checks to monitor tunnel uptime, negotiation retries, and error codes.
For larger deployments, staggering rekeys and using stable IKEv2 configurations tends to provide better reliability than older IKEv1 setups.
Regularly review VPN usage patterns to adjust firewall rules and avoid unnecessary exposure or bottlenecks.

How to verify VPN connections are working hands-on verification

From a host on the local LAN, ping a host on the remote LAN. If you receive replies, the tunnel is forwarding traffic correctly.
Use traceroute to confirm the path traffic takes across the VPN.
On the EdgeRouter CLI optional, you can view VPN status with commands like show vpn ipsec sa or show vpn l2tp status, depending on the configured method.
Check remote access client status by testing connections from multiple client devices or networks to ensure credentials and configurations work consistently.
Validate DNS resolution for VPN-connected devices to ensure name resolution works in the remote network context.
