Hello

i have two Proxmox node. not Joined to a cluster now!
DMZ 10.147.42.x
LAN 10.18.14.x

on pve-04 i wish to define another Eth Port with OVS Bridge but there i can't define a Gateway IP
so VM with a IP on the new Port would not have a Gateway. do i something wrong? do i missunderstand something?

have a nice day

You can only have one default gateway per machine.
If only VMs should use the second interface, you don't even have to set an IP and netmask for Proxmox VE.

The rest of the config needs to happen inside the VM.
