Prerequisites and checklist
Before you dive in, make sure you have:

An EdgeRouter X with the latest EdgeOS firmware 1.10.x or higher is recommended for improved VPN support
A reliable internet connection with a static WAN IP or a properly configured dynamic DNS
A small pool of private IP addresses for VPN clients for example 10.8.0.0/24
A user account with admin access on the EdgeRouter for CLI changes
A pre-shared key PSK you’ll use for IPsec
A basic firewall plan that won’t block VPN traffic and won’t expose your network
A backup plan: save a copy of your current EdgeRouter config before making changes

Why EdgeRouter X and L2TP/IPsec?

EdgeRouter X is affordable and powerful enough for small-to-medium home or small office use
L2TP/IPsec remote-access VPN is widely supported by Windows, macOS, iOS, and Android
IPsec site-to-site VPN lets you securely connect two offices or a home network to an office network

Note on features and alternatives

OpenVPN server on EdgeRouter X is not officially advertised in the EdgeOS UI, and its setup can be non-trivial. This guide focuses on L2TP/IPsec for broad compatibility and easier client configuration.
WireGuard support on EdgeRouter X exists in newer EdgeOS builds in some deployments, but availability can vary by firmware and hardware. if you’re curious about WireGuard, check your firmware release notes and community discussions for the latest status.

Step-by-step: configure remote-access L2TP/IPsec VPN on EdgeRouter X CLI workflow
This section walks you through a practical, copyable set of steps to enable remote-access L2TP/IPsec VPN for users. The commands assume you’re starting from a clean, basic EdgeRouter setup.

Prepare and create VPN user accounts

Create local VPN users who can authenticate to the L2TP server:
set vpn l2tp remote-access authentication local-users username user1 password ‘yourStrongPassword’
set vpn l2tp remote-access authentication local-users username user2 password ‘anotherStrongPassword’

Create a VPN client IP pool

Define the IP range that will be assigned to VPN clients when they connect:
set vpn l2tp remote-access client-ip-pool start 10.8.0.10
set vpn l2tp remote-access client-ip-pool end 10.8.0.100

Enable L2TP remote access and set the PSK

This PSK provides the shared secret for IPsec:
set vpn l2tp remote-access ipsec-settings ike-lifetime 3600
set vpn l2tp remote-access ipsec-settings keylife 3600
set vpn l2tp remote-access ipsec-settings pre-shared-key ‘YourPresharedKey’

Allow VPN traffic through the firewall

You’ll need to permit L2TP UDP 1701 and IPsec UDP 500 and 4500, NAT-T on the WAN side. The exact firewall zone names may vary. adapt to your setup:
set firewall name WAN_LOCAL rule 20 action accept
set firewall name WAN_LOCAL rule 20 description “Allow L2TP UDP 1701”
set firewall name WAN_LOCAL rule 20 protocol udp
set firewall name WAN_LOCAL rule 20 destination-port 1701
set firewall name WAN_LOCAL rule 21 action accept
set firewall name WAN_LOCAL rule 21 description “Allow IPsec UDP 500/4500”
set firewall name WAN_LOCAL rule 21 protocol udp
set firewall name WAN_LOCAL rule 21 destination-port 500
set firewall name WAN_LOCAL rule 22 action accept
set firewall name WAN_LOCAL rule 22 description “Allow IPsec UDP 4500 NAT-T”
set firewall name WAN_LOCAL rule 22 protocol udp
set firewall name WAN_LOCAL rule 22 destination-port 4500

Note: If you’re using a different firewall naming scheme or zones, map these rules to the correct WAN_LOCAL or equivalent firewall policy. The core idea is: allow UDP 1701, UDP 500, UDP 4500, and if behind NAT, UDP 4500 NAT-T traffic.

Enable the L2TP remote-access VPN

Activate the remote-access VPN service:
set vpn l2tp remote-access enable

Make sure the EdgeRouter knows to route VPN traffic

If your VPN clients should reach the LAN, you may need a static route or NAT rule to ensure traffic to the LAN from VPN clients is properly handled. A typical approach is:
set nat source rule 10 source address 10.8.0.0/24
set nat source rule 10 translation address masquerade
If your VPN clients should access the public internet via your home router, you may want to ensure your default route points to the EdgeRouter’s WAN gateway when VPN is active.

Save and apply the configuration

Save your changes and apply:

Test the connection

From a Windows, macOS, iOS, or Android device, configure L2TP/IPsec VPN:
- Server: your public IP or dynamic DNS hostname
- L2TP secret: not used in MS-CHAP-based setups. instead you’ll supply the PSK in the IPsec settings
- IPsec pre-shared key: YourPresharedKey
- VPN type: L2TP over IPsec
- Username/password: user1 or user2
Try connecting. If you see connection failures, review logs on EdgeRouter tail -f /var/log/messages and adjust firewall rules or PSK as needed.

Step-by-step: optional IPsec site-to-site VPN if you have another site
If you’re linking two offices, you’ll likely want a site-to-site VPN in addition to remote-access. This section gives you a clean blueprint, but keep in mind SSID-specific or router-specific quirks.

Define the remote peer and encryption settings

On EdgeRouter X, you’ll typically configure a crypto map-style IPsec peer and a tunnel for site-to-site:
set vpn ipsec ipsec-interfaces interface eth0
set vpn ipsec site-to-site peer 203.0.113.2 authentication mode pre-shared-secret
set vpn ipsec site-to-site peer 203.0.113.2 authentication pre-shared-key ‘SiteToSitePSK’
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 local-address 203.0.113.1
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 remote-address 203.0.113.2
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 local-id 203.0.113.1
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 remote-id 203.0.113.2
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 proposal 1 encryption aes128
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 proposal 1 hash sha1

Define local and remote subnets

Local side your EdgeRouter X LAN:
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 local-subnet 192.168.1.0/24
Remote side the other site:
set vpn ipsec site-to-site peer 203.0.113.2 tunnel 1 remote-subnet 192.168.2.0/24

Ensure firewall and NAT allow site-to-site traffic

You’ll need to permit IPsec and related traffic as with remote-access. The rules will look similar and should be aligned with your WAN_LOCAL policies.

Save and test

Save the config and verify the tunnel status:
show vpn ipsec sa
tail -f /var/log/messages
Generate traffic across the tunnel pinging a remote-host across VPN or transferring a file to confirm stability.

Client connection tips and caveats

Windows: Use built-in L2TP over IPsec. When you configure, you’ll supply the pre-shared key PSK and user credentials. If you see “The L2TP connection attempt failed because the security layer encountered a processing error,” re-check your PSK and ensure the EdgeRouter firewall allows UDP 1701, 500, and 4500.
macOS: Create a new VPN connection with L2TP over IPsec, entering the PSK and user credentials. macOS tends to be a little pickier about PSK length and complexity—keep your PSK strong but memorable.
iOS: iOS supports L2TP over IPsec in Settings > General > VPN. Enter the server address, remote ID if needed, and PSK. Use the same user credentials you created on the EdgeRouter.
Android: Android’s VPN settings support L2TP/IPsec PSK. Some devices require you to disable certain VPN optimization features for proper stabilization.
Troubleshooting tip: If you can connect but traffic doesn’t route through the VPN, double-check your client IP pool assignments and the EdgeRouter’s route tables. Some devices auto-default to the WAN for traffic even when the VPN tunnel is up. you may need to adjust the client-side route to force traffic through VPN.

Security best practices pragmatic, not paranoia

Use a robust pre-shared key PSK of sufficient length and randomness. avoid simple phrases.
Regularly rotate PSKs and VPN user passwords.
Limit VPN access to only the necessary user accounts and IP ranges.
Combine VPN with a firewall policy that blocks unsolicited inbound traffic. keep the WAN firewall stricter, and only allow VPN-related ports.
Keep EdgeRouter firmware up to date with the latest stable release to benefit from security and performance improvements.
Consider enabling DNS leak protection on clients by pointing VPN clients to trusted DNS servers 8.8.8.8, 1.1.1.1, etc. and disabling fallback DNS leaks in client configs where possible.
Use parallel security measures: patch devices, use strong device passwords, and enable two-factor authentication on services that support it.

Performance considerations and best practices

VPN encryption adds CPU overhead. EdgeRouter X is budget-friendly. monitor CPU usage when many clients connect or when transferring large files.
For remote-access VPN, aim for a balance between strong encryption AES-256 and performance. If you notice slow connections, consider lowering to AES-128 or adjusting IKEv2/ESP settings, while preserving a secure profile.
Ensure your internet uplink is stable. VPN performance is often limited by your WAN speed and latency rather than the VPN itself.
If you plan to host media or file shares at home and access them over VPN, consider QoS rules to prioritize VPN traffic when you’re streaming or gaming.

Real-world tips and caveats

If you’re behind a carrier-grade NAT CGNAT or do not have a static IP, using a dynamic DNS service is essential to keep the EdgeRouter reachable from the internet. Set up a DDNS client on the EdgeRouter or your gateway.
If you must connect from behind strict NAT or corporate networks that block UDP 1701, L2TP/IPsec may fail. In such cases, consider alternative options, such as IPsec site-to-site with a partner network or, if available, native WireGuard support in compatible firmware.
Documentation and community help are invaluable. Ubiquiti’s own docs are detailed, and the community forums often have practical, real-world configurations that work for home labs and small offices.

Useful testing checklist

Confirm VPN server is reachable from a remote location ping the EdgeRouter’s public IP or hostname
Verify VPN client can obtain an IP from the VPN pool
Check that the client can access LAN resources printer, NAS, Samba shares
Validate that internet-bound traffic from VPN clients routes through the VPN if desired
Monitor EdgeRouter logs for authentication failures or dropped packets and adjust firewall rules accordingly

EdgeRouter X VPN vs. open-source options

EdgeRouter X is a compact, cost-effective device that handles VPN with good reliability when configured properly. If you’re chasing the easiest setup and broad compatibility with modern clients, L2TP/IPsec on EdgeRouter X is usually simpler and widely supported.
If you’re comfortable with more experimental setups and want to run OpenVPN or WireGuard specifically, you might explore additional methods or other hardware that’s designed for those protocols. Always back up configs before trying experimental features on EdgeRouter X.
