WireGuard Not Restarting After WAN IP Change (Mullvad)

[foobarbigtime]

Hi, I've been experiencing the same issue described here where WireGuard (Mullvad in my case) goes stale after a WAN IP change.

As a workaround, I've been using a script triggered by WAN reconnect to run:

sh
Copy
Edit
service wireguard restart

This restores connectivity immediately.

Would it be possible for OPNsense to have built-in handling so WireGuard tunnels auto-restart when the WAN reconnects or the IP changes — similar to how OpenVPN handles it? This would remove the need for external scripts.

System details:

OPNsense 25.7.x

WireGuard plugin

WAN: DHCP (em0)

Hi.

The very last message before yours was about exactly the same topic.
