Optional L2TP/IPSec Settings for TP-LINK Routers

Option 1: Enable Auto-Connect on Startup

Ensure the VPN reconnects automatically after a reboot or disconnection:

  1. Go to Advanced > VPN Client.
  2. Under Reconnect Mode, select Always On.
  3. Click Save & Apply.

This ensures your VPN stays active even after a reboot or network drop.

Option 2: Selective Routing (Policy-Based Routing for Specific Devices)

By default, all connected devices use the VPN tunnel. To route only specific devices through VPNUK’s L2TP/IPSec VPN, follow these steps:

Step 1: Enable Policy-Based Routing

  1. Go to Advanced > Routing.
  2. Click Add Route and enter:
    • Destination: 0.0.0.0/0
    • Gateway: VPN Interface (VPNUK-L2TP)
  3. Click Save & Apply.

Step 2: Assign Specific Devices to the VPN

  1. Go to Advanced > VPN Client > Policy Routing.
  2. Enter the local IP addresses of devices that should use the VPN.
    • Example:
      192.168.1.100/32
      192.168.1.105/32
  3. Click Save & Apply.

Now, only selected devices will use the VPN, while others remain on the normal internet connection.

Option 3: Kill Switch (Block Internet If VPN Disconnects)

A kill switch prevents leaks by blocking internet traffic if the VPN connection drops.

  1. Go to Advanced > Firewall > Access Control.
  2. Create a new rule:
    • Protocol: All
    • Source IP: 0.0.0.0/0
    • Destination IP: 0.0.0.0/0
    • Action: Deny
  3. Click Save & Apply.

If the VPN disconnects, all internet traffic is blocked until the VPN is reconnected.

Troubleshooting Common Issues
