I need some help because the network world is still relatively new to me.
I have another new server, but unfortunately no more network ports are free. So I thought it should be possible to configure my first server as a bridge. It has two network ports.
My topology would look like this:
The network naming of Proxmox irritates me somewhat (as I said, I'm new to this environment).
The vmbr0 is already a bridge? But this accesses enp60s0. So enp60s0 would be one of the two network adapters?
Is the eno1 the second adapter or was the second one not initialized?
My network interface looks like this:
For the sake of completeness, here is my current ip addr output:
My previous attempts to create a bridge have only ever broken the network. I then always set it back to the source.
Solved: Added eno1 to the bridge.

My network interface looks like this:
Code:
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

My previous attempts to create a bridge have only ever broken the network. I then always set it back to the source.
Solved: Added eno1 to the bridge.
