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 ?

Thanks.

Hi,

Can i see output of command: cat /etc/network/interfaces

No.

Hi below:

# If you want to manage parts of the network configuration manually,

# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of

your opnSense is in a VM?
you could ping, if fail because something is disconected, rebout your opnSense-VM?!

Try to add Static mac address with ifconfig[0]

And check a firewall as well

I'll try the static mac suggestion thanks. Firewall is disabled.

Sorry, one question. What MAC would you suggest to use here. The physical NIC WAN or the MAC that Opnsense sees assigned to the bridge or something else ?

Thanks

Hi,

I tried using a static Mac within Proxmox for the WAN interface set to the same MAC as Proxmox->OpnsenseVM->Hardware->Network Device 1(net1) but didn't see, to work.

Proxmox syslog reports"

Jan 27 17:54:29 proxmox kernel: vmbr1: received packet on tap100i1 with own address as source address (addr:2f:91:65:4f:93:1f, vlan:0)

Seem's like there is some kind of clash.

Thanks
Dilby.
