Hi, I installed a brand new Proxmox 8 server and I'm trying to configure a vmvr0 with bridged port to the physical interface of the Proxmox server, this configuration works on Proxmox 7 where I've 2 public ip, 1 for the physical server and the other one for the pfsense vm hosted inside Proxmox. After applying the interfaces configuration the physical interface no longer has an ip assigned. Can you help me to solve this issue? You can find attached the interfaces configuration file. Thank you

Hi, thank you for your reply! No I bought an additional public ip with separate MAC address, physical interface have 1 public ip and vmbr0 se second with separate MAC. Thank you
In this case you don't need a bridge-ports i.e, get rid of `bridge-ports enpXs0` line in the network config.

auto vmbr0
iface vmbr0 inet static
    address  X.X.X.X
    gateway  X.X.X.X
#    bridge-ports enpXs0
    bridge-stp off
    bridge-fd 0
    post-up echo 1 > /proc/sys/net/ipv4/ip_forward
