Hi,

recently I got my new minipc which I want to turn into a virtualized OPNsense router with some additions like pihole.
As my router will be virtualized I thought it would be a good Idea to dedicate one of the 4 ethernet ports to management.
The idea was to be able to access the proxmox UI even if the OPNsense VM crashed through a direct P2P connection.

My current Proxmox network config looks like this (`enp5s0` should be the management port):

Accessing Proxmox via `vmbr0` (`enp2s0`) works as expected. But as soon, as I connect my pc to `enp5s0` (though a switch to mitigate crossover problems) and want to access the Proxmox UI with the different IP I cannot access it. I can't even ping the IP.

My PC uses fedora 38 with KDE and the Interface is configured this way:

What am I doing wrong here?
 
OK, I found a solution shortly after posting myself.
I removed the IP from `enp5s0` and created another bridge for on that NIC with the IP instead:
