What you’ll get: a secure remote connection, centralized user access, and a VPN that works with most devices Windows, macOS, iOS, Android.
This guide includes: prerequisites, firewall rules, IP addressing, certificate considerations, user authentication, testing, and troubleshooting.
What you’ll see: a straightforward, step-by-step approach, practical commands, a few tables for reference, and a small FAQ at the end.

Prerequisites and assumptions

EdgeRouter model running EdgeOS latest stable firmware recommended.
A static public IP address or a dynamic DNS hostname pointing to your EdgeRouter.
A LAN subnet that does not conflict with the VPN subnet you plan to use.
Admin access to the EdgeRouter via SSH or the GUI.
Basic understanding of networking concepts: IP ranges, DNS, NAT, firewall rules.
A DNS name for the VPN server is optional but recommended for easier client configuration.

Recommended network plan

VPN server subnet: 192.168.50.0/24 example
VPN clients will get addresses from 192.168.50.100–192.168.50.200 adjust as needed
Your LAN remains on 192.168.1.0/24 adjust to your network

Step-by-step setup CLI approach

System readiness

Ensure NTP is accurate so certificates if used stay in sync.
Confirm your EdgeRouter firmware is up to date.

Create VPN IP pool

This creates a pool of IPs for VPN clients.
Example:
- set vpn ipsec ipsec-psk ‘your_pre_shared_key’
- set vpn ipsec ike-password ‘your_ike_password’ optional, depending on your setup
- set vpn l2tp remote-access authentication mode local
- set vpn l2tp remote-access authentication local-users username vpnuser password vpnpass
- set vpn l2tp remote-access ipsec-settings ike-library ‘default’
- set vpn l2tp remote-access ipsec-settings ike-version v2
- set vpn ppp enable
- set vpn l2tp remote-access ipsec-settings ike-cipher ‘aes128’
- set vpn l2tp remote-access ipsec-settings esp-cipher ‘aes256’
- set vpn l2tp remote-access ipsec-settings pfs ‘group2’
- set vpn l2tp remote-access name-server 8.8.8.8
- set vpn l2tp remote-access ipsec-settings hash ‘sha256’
- set vpn l2tp remote-access ipsec-settings lifetime ‘3600’
Note: The exact commands can vary; EdgeRouter uses a combination of vpn l2tp and ipsec settings. If you’re using a GUI approach, translate these concepts accordingly.

L2TP server configuration

Enable L2TP for remote access and tie it to the IP pool and authentication you defined.
set vpn l2tp remote-access enable
set vpn l2tp remote-access authentication mode local
set vpn l2tp remote-access authentication local-users username vpnuser password vpnpass
Define IP pool if you plan to allocate addresses automatically to clients.

IPsec configuration

IPsec pre-shared key or certificates
set vpn ipsec ike-group IKE_GROUP dead-peer-detection time 10
set vpn ipsec ike-group IKE_GROUP proposal aes128-sha256
set vpn ipsec esp-group ESP_GROUP proposal aes256-sha256
set vpn ipsec sa duration 3600
set vpn ipsec site-to-site peer your_peer_ip authentication mode pre-shared-secret
set vpn ipsec site-to-site peer your_peer_ip authentication pre-shared-secret your_pre_shared_key
set vpn ipsec site-to-site peer your_peer_ip ike-group IKE_GROUP
set vpn ipsec site-to-site peer your_peer_ip esp-group ESP_GROUP
Note: For L2TP over IPSec, you typically configure a global IKE/IPSec profile and then bind L2TP to IPSec for the tunnel.

Firewall and NAT rules

Allow UDP ports 1701 L2TP, 500 and 4500 IPSec through the firewall on the WAN interface.
If you’re behind NAT, ensure NAT-T is enabled for IPsec.
Example:
- set firewall name WAN_IN rule 10 protocol udp
- set firewall name WAN_IN rule 10 destination-port 1701
- set firewall name WAN_IN rule 10 action accept
- set firewall name WAN_IN rule 11 protocol udp
- set firewall name WAN_IN rule 11 destination-port 500
- set firewall name WAN_IN rule 11 action accept
- set firewall name WAN_IN rule 12 protocol udp
- set firewall name WAN_IN rule 12 destination-port 4500
- set firewall name WAN_IN rule 12 action accept
Attach WAN_IN to the WAN interface: set interfaces ethernet eth0 firewall in name WAN_IN
Ensure LAN firewall rules allow VPN clients to access required internal subnets if necessary.

Routing and NAT

Ensure VPN clients can reach your LAN.
Example: add a static route or enable policy-based routing as needed.
If you want clients to access the internet through the VPN, enable NAT for VPN clients:
- set nat source rule 100 outbound-interface eth0
- set nat source rule 100 source address 192.168.50.0/24
- set nat source rule 100 translation address masquerade

DNS considerations

Decide whether VPN clients should use your home/office DNS or public DNS.
You can push DNS settings to clients or configure the VPN to supply DNS.

Authentication approach

Local users: add VPN users locally on EdgeRouter with usernames and passwords.
Radius or LDAP: if you need centralized auth, consider integrating with a RADIUS server.
Strong passwords and, if possible, MFA for remote access.

Certificate-based option optional but recommended

If you want to use certificates instead of/alongside PSK for IPSec, you’ll:
- Generate CA, server, and client certificates
- Import certificates to EdgeRouter
- Configure IPsec to use certificate-based authentication
Certificates add an extra layer of security over PSK.

Verification steps

On client: connect using L2TP over IPSec with the PSK or certificate
Confirm tunnel status on EdgeRouter:
- show vpn ipsec sa
- show vpn l2tp remote-access
Validate connectivity:
- Ping a device on the remote network from the client
- Check if the client obtains an IP in the VPN pool
Check logs if the connection fails:
- show log
- examine messages related to L2TP, IPSec, and IPsec SA establishment

Common issues and fixes

Issue: L2TP connection times out
- Fix: Ensure UDP 1701 is open, and IPsec ports 500 and 4500 are allowed. Confirm NAT-T is enabled.
Issue: IPSec SA not established
- Fix: Verify pre-shared key, IKE settings encryption, hash, DH group, and ensure the remote peer matches EdgeRouter config.
Issue: VPN client cannot reach LAN devices
- Fix: Check route back to VPN subnet, ensure proper firewall rules, and verify that the VPN subnet is not overlapping with LAN subnets.
Issue: DNS resolution fails for VPN clients
- Fix: Push or configure DNS servers correctly in the VPN settings.

Security hardening tips

Use a strong pre-shared key if you’re not using certificates. Rotate it periodically.
Prefer certificate-based authentication if possible.
Restrict VPN access by IP or device type when feasible.
Monitor VPN login attempts and enable logging for security events.
Regularly review firewall rules and keep EdgeRouter firmware up to date.

Performance considerations

L2TP over IPSec adds overhead; ensure your EdgeRouter has enough CPU and memory for your user load.
For many concurrent connections, consider upgrading to a router with better hardware or offloading VPN tasks to capable devices.

Monitoring and maintenance

Regularly check VPN connection health and performance metrics.
Review VPN client connection logs for failed attempts and patterns.
Back up EdgeRouter configurations after a successful VPN setup.

Tips for Windows, macOS, iOS, and Android clients

Windows: Create a VPN connection using L2TP over IPSec with your server’s public IP or hostname and the PSK.
macOS: Similar steps as Windows; you can export/import configuration if needed.
iOS/Android: Use built-in VPN settings to add L2TP over IPSec with the server address and PSK.

Advanced configuration options

Split tunneling: Decide whether only VPN traffic goes through the tunnel or all traffic routes via VPN.
Client-specific routes: Route only certain subnets through the VPN if you want finer control.
Multi-factor authentication: Combine with an MFA solution that supports VPN authentication.

Comparison with other VPN solutions

L2TP/IPSec is easier to set up than OpenVPN on some EdgeRouter setups but may be less flexible than WireGuard in terms of performance and simplicity.
For sites requiring site-to-site compatibility, IPsec with strong authentication is a solid option, but each network topology may require adjustments.

Alternative approaches

WireGuard: If you’re seeking modern, high-performance VPN on EdgeRouter, you can explore WireGuard as an alternative to L2TP/IPSec.
OpenVPN: A robust alternative with broad client support, though configuration on EdgeRouter may be more involved.

Maintenance checklist

Verify firmware and security patches are current.
Review VPN user accounts and remove outdated users.
Test failover and VPN recovery after any network changes.

Troubleshooting quick-reference

No VPN client connection: verify credentials, PSK, and port availability.
Clients connect but no access to LAN: review route configuration and firewall rules.
Intermittent VPN disconnects: check keepalive settings and network stability.

Networking best practices

Use a dedicated VPN subnet to prevent conflicts with LAN subnets.
Maintain clear documentation of your VPN settings, user accounts, and IP ranges.
Regularly rotate credentials and monitor access logs for unusual activity.

Note on naming and wording

The guide uses consistent terminology for EdgeRouter, L2TP, and IPSec, focusing on practical, real-world steps and common edge cases.

Step 7: Firewall rules and NAT adjustments
- Allow UDP ports 500 and 4500 for IPsec and UDP 1701 for L2TP.
- Create firewall rules to permit VPN traffic on the WAN interface and to ensure VPN traffic is not blocked by default policies.
- Example rules conceptual, adapt to your existing firewall structure:
  - set firewall name WAN_LOCAL rule 10 allowed-udp protocol udp destination-port 500
  - set firewall name WAN_LOCAL rule 20 allowed-udp protocol udp destination-port 4500
  - set firewall name WAN_LOCAL rule 30 allowed-udp protocol udp destination-port 1701
- Then apply:
Step 8: Verify the VPN server is listening
- On EdgeRouter, you can check the status of the L2TP server and related IPsec settings via the CLI or Web UI. Look for the L2TP server status and IPsec sa security association status.
Step 9: Client-side configuration basics
- Windows/macOS/iOS/Android clients require:
  - Server public IP or hostname
  - Username and password
  - IPsec pre-shared key PSK
- Windows and macOS typically use built-in L2TP/IPsec clients. iOS and Android also have native L2TP/IPsec support.
Step 10: Testing the tunnel Built-in vpn for OS-level protection: how to use built-in VPN on Windows, macOS, iOS, Android, and best practices 2026
- Connect a client, verify the VPN tunnel is established, check the assigned client IP from 192.168.50.0/24 in our example, and test access to LAN resources or public IP to ensure traffic is flowing through the VPN.

Important notes:

If you’re behind double NAT or behind a CGNAT scenario at the ISP, you’ll need to ensure the EdgeRouter is reachable on its public IP and not blocked by upstream NAT.
Some networks block L2TP/IPsec by design. If you run into connection issues, test from a different network or consider an alternative like OpenVPN or WireGuard.
