[SOLVED] Problem with no linux bridge

[Tim1]

Hello together,

I added a new nvme to proxmox.
The Interface was renamed.

But now I have this configuration and no linux bridge.
I don't know at the moment how to fix the Problem.

Shell shows this:

auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet static
address 192.168.178.48/24
gateway 192.168.178.1
bridge_ports enp2s0
bridge_stp off

Gui show this:




Can someone help?

bridge_ports enp2s0

You have to change this line as well.

Then do ifreload -a command.

Sure?

May you post the output of the ip a command the current network configuration as well cat /etc/network/interfaces?

Thank you for the output!

Your network config is missing this line `iface enp3s0 inet manual` i.e. your network configuration should look like the following:

auto lo
iface lo inet loopback




iface enp3s0 inet manual




auto enp3s0
iface enp3s0 inet static
address 192.168.178.48/24
gateway 192.168.178.1
bridge_ports enp3s0
bridge_stp off

I added, but also Errors here.
