Proxmox 6 - Debian 10 VPS netwrok configuration

[higi22]

Hello,

- have OVH.com dedicated server with Proxmox 6 installed.
- ordered 64 IP block

My VPS are configured (on proxmox GUI side):
- Bridge vmbr0
- Model: VirtIO
- MAC adress: xx.x.x.x.x..x (generated on OVH side, virtual MAC)

My network configuration on VPS side:

cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo eth0
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 54.37.XX.YY
        netmask 255.255.255.255
        broadcast 54.37.XX.YY
        post-up route add 51.AA.BBB.254 dev eth0
        post-up route add default gw 51.AA.BBB.254
        pre-down route del 51.AA.BBB.254 dev eth0
        pre-down route del default gw 51.AA.BBB.254
        # dns-* options are implemented by the resolvconf package, if installed
        dns-search 213.186.33.102 212.127.32.132 8.8.8.8

Everything is working great, VPS Deabin 9 are online and have internet access on public IP.

My problem is when i install VPS Debian 10, using same configuration as on Debian 9, VPS cannot access internet, cannot ping on google etc.

Please help.
THX

netmask 255.255.255.255

You will need a gateway in your network, so maybe with netmask 255.255.255.252
