I have opnsense in proxmox and i had it working fine for couple of days, I was just connected to its lan via vpn, suddenly it stopped working and didnt even get a public address or even serve local addresses to devices connected to its lan, so i thought maybe my vpn connection has a problem so i log in to vnc console of opnsense and ping wan gateway and lan gateway they were unreachable, so I restarted whole proxmox server thinking maybe a restart should solve it but it didnt. the strange thing is i didnt change any settings or do anything to configuration of any vm or pve or opnsese, i was simply connected ssh of a vm that was and doing a build on it so nothing related to networking or settings, after transferring wan ip to proxmox and it worked instantly as expected so it wasnt a problem with ip, i then restored wan connection to opnsense and changed lan ip address but still none of the devices connect to it, i checked that all vm and lan share same bridge so they should get ip from dhcp server on opnsense but they didnt, so i try to change lap ip address from 10.10.10.1/24 to 192.168.1.1/24 and magically it started working again and internet restored to lan devices.

What should i look for in logs ?
any ideas why this happened ?

When opening the firewall management page from within local network i can view all settings and change anything, but when connecting to the same management page through vpn connection, i can only view limited gui management page and not all options appear as they normally do.
any ideas what is wrong or how to fix it ?
