Network issue - fresh install

[HexXn1]

Hello,

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 10.0.10.10/24 and gateway to 10.0.10.1. Tried DNS as the same as gateway as well as just 1.1.1.1. When up and running I cannot ping the gateway or anything else. I cannot access https://10.0.10.10:8006 from another machine.

If I plug the ethernet cable into a Windows machine it gets the IP 10.0.10.200 with gateway 10.0.10.1. 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
        address 10.0.10.10/24
        gateway 10.0.10.1
        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
