Surfshark Wireguard (lan client) crashing OPNsense

[Mazman]

Hello everyone, I've been using OPNsense for a few months now and have really been enjoying it.

I'm currently on OPNsense 23.1.3-amd64

I came across an issue a day ago while using Surfsharks Wireguard VPN on a lan computer. It has no problem connecting and the speeds are excellent on my gigabit fiber network.

However, after a few minutes of being enabled, I loose all internet system wide. Disconnecting doesn't fix this.

The firewal becomes completely inaccessible, not giving out any local DHCP leases. I can't ping it, even from a static local IP. I end up having to physically reboot it to get it to work again.

I'm not sure how a Wireguard client is taking down OPNsense as I don't see anything in the logs.

I do have OpenVPN configured but I don't see how that would cause this issue.

Please let me know if you have any ideas and/or need any logs or configurations.
