Hello,
I recently configured a Proxmox 8.1 server with 2 network interfaces with two different networks

Bash:
auto lo
iface lo inet loopback

iface eno8303 inet manual

iface eno8403 inet manual

iface eno12399np0 inet manual

iface eno12409np1 inet static

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.140/24
        #gateway 192.168.1.9
        bridge-ports eno8303
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address 192.168.10.140/24
        gateway 192.168.10.9
        bridge-ports eno8403
        bridge-stp off
        bridge-fd 0

The problem arises when the interface vmbr0 is disconnected, since the connection is also lost on the interface vmbr1
