Network issue - fresh install


New Member
Nov 8, 2023

I recently built a machine to run Proxmox, but it appears to be suffering from some network issue.

The motherboard has 1x realtek port and 1x intel. Decided to use the intel one. I set the IP to and gateway to Tried DNS as the same as gateway as well as just When up and running I cannot ping the gateway or anything else. I cannot access from another machine.

If I plug the ethernet cable into a Windows machine it gets the IP with gateway I can ping the machine.

Some help would be appreciated, thank you!

Using vlans, managed to solve it by:

auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

iface enp0s31f6.10 inet manual

auto vmbr0v10
iface vmbr0v10 inet static
        bridge-ports enp0s31f6.10
        bridge-stp off
        bridge-fd 0

auto vmbr0
iface vmbr0 inet manual
        bridge-ports enp0s31f6
        bridge-stp off
        bridge-fd 0

iface enp3s0 inet manual

iface wlp0s20f3 inet manual
