Proxmox + Opnsense WAN interface not refreshing

[dilby]

Hi,

I'm have Opnsense running on proxmox acting as a firewall and router. My system has two NICs one for WAN and one for LAN. The issue i'm facing is that if my cable modem requires a restart after a crash, I also have to restart the opnsense guest or disable and then re-enable the WAN interface within opnsense.

The issue seems to be that opnsense is still seeing the proxmox Linux Bridge to the WAN interface as being connected (even if the modem is switched off) and not requesting a new lease unless I force it manually.

Is there a way for the bridge to "disconnect" if the physical interface is disconnected ?

I had a search around on the net and seems to be a common issue with some modems being tied to MAC address, but i've tried to spoof the physical MAC within Opnsense WAN interface page and makes no difference.

Thanks.
