What EdgeMax VPN support looks like in 2025
EdgeOS on EdgeMax devices provides built-in VPN capabilities that are well-suited for small to medium networks. You’ll typically find:

• IPsec site-to-site VPN for connecting two office networks or a home lab to a remote site
• OpenVPN server to allow remote clients to connect to your network
• OpenVPN client mode to connect the EdgeMax router itself to an upstream OpenVPN server
• Less commonly used L2TP/IPsec as a VPN option for certain clients and legacy setups
  The performance you get depends a lot on the hardware EdgeRouter vs EdgeRouter X vs higher-end units, cipher choices, and how many tunnels you run simultaneously. Real-world users report stable tunnels with speeds ranging from tens to hundreds of Mbps on mid-range gear, with hardware upgrades or offloading features delivering better results.

VPN types explained when to use what

• IPsec site-to-site: Best for linking two networks. Once configured, devices on both sides route through the VPN tunnel. No user credentials required after the tunnel is up. it’s all device-to-device.
• OpenVPN server remote access: Great when you need individual devices to connect to your network from anywhere. You’ll typically install OpenVPN client software on laptops, phones, or other devices and point them to the EdgeMax OpenVPN server.
• OpenVPN client to upstream server: Useful if your EdgeMax device needs to connect to an external VPN service or another OpenVPN server you control. Keeps your EdgeMax network traffic pooled through the remote VPN endpoint.
• L2TP/IPsec: A simpler alternative for some clients, though IPsec alone can be enough for many setups. If you’re supporting devices that only support L2TP, this can be handy.

Step-by-step setup: IPsec site-to-site VPN GUI path
Note: this is a common, robust option for linking two sites. You’ll configure the tunnel, define the VPN peer, set phase 1/2 settings, and add firewall and static routes.

1. Prepare the shared details

• Remote network/subnet: the LAN behind the other EdgeMax router
• Remote device IP or hostname: the public IP or DNS name of the peer
• Pre-shared key PSK: a strong random key for the tunnel
• Encryption and hashing preferences: AES-256, SHA-256, DH group 14 or higher
• IKE version: IKEv2 is preferred where available. IKEv1 can work in older setups

2. GUI path to set up IPsec

• Log in to EdgeOS, go to VPN > IPsec
• Enable IPsec and add a new TUNNEL or PEER, depending on your firmware terminology
• Set Peer IP: the remote public IP or hostname
• Set Local Network: your LAN e.g., 192.168.1.0/24
• Set Remote Network: the remote LAN e.g., 192.168.2.0/24
• Enter PSK: your shared secret
• IKE Group: choose a secure value e.g., 14
• ESP Group: AES-256, 256-bit
• PFS: enabled Group 14 or higher
• Enable the tunnel and apply changes

3. Firewall rules and routing

• Add a firewall rule to allow VPN traffic UDP 500, UDP 4500, and ESP
• Create or adjust a static route so return traffic goes through the VPN:
  • Destination: remote network
  • Next hop: VPN tunnel interface
• Apply and test with a ping across the tunnel from a host on each side

4. Verify the tunnel

• In EdgeOS, check the VPN status UI for up/down
• Use a packet test e.g., ping a host on the remote side to confirm traffic flows
• If you don’t see traffic, double-check ISAKMP/IKE and ESP policies and the remote peer config

Step-by-step setup: IPsec site-to-site VPN CLI path
If you prefer the CLI, here’s a compact sequence you’ll adapt to your values. Replace placeholders with your real data.

• Enable VPN interfaces and policies
  set vpn ipsec ipsec-interfaces interface eth0
  set vpn ipsec ike-group IKE-GROUP1 lifetime 3600
  set vpn ipsec ike-group IKE-GROUP1 proposal 1 encryption aes256
  set vpn ipsec ike-group IKE-GROUP1 proposal 1 hash sha256
  set vpn ipsec esp-group ESP-GROUP1 lifetime 3600
  set vpn ipsec esp-group ESP-GROUP1 proposal 1 encryption aes256
  set vpn ipsec esp-group ESP-GROUP1 proposal 1 hash sha256
  set vpn ipsec site-to-site peer PEER1 authentication mode pre-shared-secret
  set vpn ipsec site-to-site peer PEER1 authentication pre-shared-secret ‘your_psk_here’
  set vpn ipsec site-to-site peer PEER1 address ‘REMOTE_PUBLIC_IP’
  set vpn ipsec site-to-site peer PEER1 local-address ‘YOUR_PUBLIC_IP’
  set vpn ipsec site-to-site peer PEER1.

  Set vpn ipsec site-to-site peer PEER1 ike-group IKE-GROUP1
  set vpn ipsec site-to-site peer PEER1 esp-group ESP-GROUP1
  set vpn ipsec site-to-site peer PEER1 local-subnet 192.168.1.0/24
  set vpn ipsec site-to-site peer PEER1 remote-subnet 192.168.2.0/24

Step-by-step setup: OpenVPN server remote access
Remote access OpenVPN is a solid choice if you want individual devices to connect to your network.

1. Prepare the OpenVPN server on EdgeOS

• In EdgeOS GUI: VPN > OpenVPN > Server
• Enable the server, choose port 1194 UDP is standard, protocol, and certificate settings
• Create a server certificate or use an existing one. EdgeOS will generate a CA if you don’t have one
• Define the VPN subnet for clients, e.g., 10.8.0.0/24

2. Client configuration

• Generate client certificates/certs for each device, or use a standard .ovpn profile if your version supports it
• Provide the .ovpn file to clients or manually configure their OpenVPN client with the server IP, port, and PSK

3. Firewall rules

• Permit UDP 1194 or your chosen port in the firewall
• Allow traffic from VPN clients to your internal subnets

4. Test

• Start the OpenVPN server and connect a client
• Verify ping to a device on your LAN from the VPN client
• Check the EdgeOS OpenVPN status page for connected clients

Step-by-step setup: OpenVPN client EdgeMax to upstream server
If you want EdgeMax to connect to another OpenVPN server e.g., to route EdgeMax traffic through a remote VPN, set up the client mode.

1. OpenVPN client config

• In EdgeOS: VPN > OpenVPN > Client
• Enter server address, port, protocol, and credentials or client certificate if required
• Define the local and remote networks for route propagation

2. Firewall and routes

• Add route rules to push traffic destined for the remote network through the OpenVPN client interface
• Ensure firewall rules allow traffic from VPN client to internal subnets

3. Test

• Check client status, ping remote LAN devices through the tunnel, and confirm the route is active

L2TP/IPsec as an alternative
Some setups or devices favor L2TP/IPsec because it’s widely supported on many clients. If your EdgeOS version supports L2TP/IPsec, you can configure it similarly to IPsec site-to-site or as a remote access method. Keep in mind that L2TP/IPsec can be slower and may be less secure than modern IPsec configurations. If you’re aiming for simplicity and broad client compatibility, IPsec and OpenVPN are usually the better bets.

Performance and security tips

• Choose strong encryption and DH groups: AES-256, SHA-256, and DH Group 14 or higher for your IKE. This provides robust security without crushing performance on mid-range hardware.
• Enable Perfect Forward Secrecy PFS for additional forward secrecy in IPsec
• Keep firmware current: EdgeOS updates often include security fixes and VPN improvements
• Limit VPN access: only allow necessary subnets and VPN users. avoid broad access to your entire LAN
• Split-tunnel where appropriate: route only required traffic through VPN to reduce load and preserve speed
• Regularly audit VPN peers and client certificates. revoke old or compromised keys promptly
• Use DNS and split-horizon strategies to avoid leaking internal DNS requests

Security hardening checklist quick

• Disable PPTP and any weak VPN protocols
• Use strong, unique PSKs or certificates
• Regularly rotate keys and certificates
• Disable remote management from the WAN interface unless you need it
• Monitor VPN activity with the EdgeOS logs and VPN status pages

Monitoring and troubleshooting basics

• Check tunnel status in the EdgeOS dashboard under VPN or IPsec pages
• Verify that firewall rules permit VPN traffic ESP, ISAKMP, UDP 500/4500, and OpenVPN ports if used
• Test with ping and traceroute to confirm traffic path through the VPN
• If the tunnel won’t come up, verify:
  • Peer IP/hostname is reachable
  • PSK or certificate is identical on both ends
  • Subnet definitions don’t overlap
  • IKE/ESP policies on both sides match

Data and usage notes
VPN adoption has grown as more people work remotely and want secure site-to-site connectivity. Industry voices consistently note a rise in VPN adoption in home labs and small offices, with EdgeOS users particularly benefiting from a flexible, cost-effective solution. Hardware capability is the main driver of performance: mid-range EdgeRouter devices typically handle tens to hundreds of Mbps of VPN traffic depending on the cipher suite and whether you’re using OpenVPN vs IPsec. In well-tuned setups, you can expect reliable, low-latency tunnels that support everyday remote work, file transfers, and private network access without adding noticeable lag.

Best practices for long-term success

• Plan your topology: decide upfront if you’re doing site-to-site, remote access, or both
• Centralize certificate management if you’re using OpenVPN with many clients
• Document all VPN configurations: peers, subnets, keys, and firewall changes
• Periodically review and prune unused tunnels and old keys
• Consider a small, redundant backup for the VPN endpoints if uptime is mission-critical
