I can't figure out how to do this to save my life...

[formerflyboy]

I have a Dell Poweredge r720 with Proxmox as the base and I'm trying to install OPNsense in a VM to do it's job.  My issue is that I can't figure out how to get around the problem of losing connection to Proxmox when I connect the modem to one port and the LAN to the other.  I end up having to start from scratch and reinstalling Proxmox to get the LAN connection back up.

Anybody else ever have an issue like this and how did you solve it?

Thanks.

not sure if i understand.

You are running your router in a VM. Your host (proxmox) will boot first and needs a network too. But your router is not available at this (boot) moment. AFAIK proxmox force a hard IP at installation time. Make sure this IP is outside of your DHCP range but IN the correct network.

Network is a integral important part of your infrastructure. Personally i would just use some dedicated mini computer for it.

This will help, got it working on mine with NO issues  (also go into options and set OPNsense to boot as 1 so it's the first VM that boots as soon as the PROXMOX system is up, all the others have start with a delay and sequentially)

I also have another nic (the onboard nic of mobo) set as an internal IP, so I can get to the PROXMOX, but the other PCI passthru to the OPNsense for firewall are isolated from the PROXMOX OS itself
