Firewall Deactivation/Activation

[spetrillo]

Hello all,

I currently have a physical firewall running. I have built a virtual firewall but my question has to do with deactivating the physical firewall and letting the virtual firewall become the active firewall. How do I do this?

Thanks,
Steve

Hi Steve, I would disable the LAN interface or give it a different IP using the console. Then assign its old IP to the VM and test.

I tried that but no go. I even put my PC on the same vlan as the LAN interface of the newly built virtual firewall, but no go. Not sure how I am going to do this.

Which hypervisor? Do you get anything from the VM console?

I am running Proxmox 8.2.7. The vm boots up properly but I am not able to ping any of the internal LAN segments on the OPNsense VM. I am going to try to build a desktop vm on the same vlan as the LAN segment of the OPNsense VM and see what happens.

So I built a simple Ubuntu 22.04 desktop. I set the network config as a manual IP and my gateway as the LAN IP of the OPNsense VM. No go...I cannot ping the OPNsense VM from the desktop and vice versa. This is very confusing to me. I am going to hit the Proxmox forum, to see what ppl say over there.

This should not be rocket science...

There are a few choices in the Proxmox + OPNsense setup and it may be worth stepping through your build next to a known good process.
