wireguard 3g wan & crashes on reboot/shutdown

[keropiko]

Hello, i have a 20.1.3 setup, with multiwan (pppoe,3g ppp and dhcp). I have setup a mullvad wireguard vpn, with interface setup, disabled auto routing and created a gateway (1.9.9.1) setup as wireguard gateway on the Local wireguard settings. Everything including the wireguard vpn is working okay.

The problem is when i try to reboot or shutdown the machine. It hangs without responding on console or it crashes and then reboots.

I don't know what to look. What i have noticed, is that after the crash the 3g does not connect (the usb stick is blocked on the old connection so i have to reset or unplug it). If i reboot it while the 3g connection is not working, it does not crash.

The thing is that before installing the wireguard vpn, with the 3g connection there were no problems rebooting.

The problem only exists when both the 3g ppp connection and wireguard vpn are working.

I would like some help how to resolve this issue.

I have submited the crashes with the button so i don't know if that helps.
Thank you.

Hello all,

i have resolved temporaly the problem by disabling the gateway monitor at the wireguard and the 3g ppp gateway.

With gateway monitoring enabled to wireguard and/or 3g usb gateway, when i try to reboot or shutdown the firewall crashes.

If i disable monitoring on both gateways then i can reboot snd shutdown normaly.

If someone with similar setup can verify please so we can open a bug case.

Thank you.
