Hi guys!
I am new to Proxmox and just learning the basics. I once had help with installing proxmox 7 and setting it up initially, but time goes by and I eventually updated PRoxmox to version 8.
Now it's time to add some hardware to the server and due to changes in the BIOS settings regarding pci, the network devices were apparently renamed.
Everything would be fine, I found working ones, changed the file /etc/network/interfaces and the network somehow worked.
However, I would like to completely reset all network parameters to set up the network again from scratch.
My file now looks like this:
lspci | grep Ethernet output:
I have two built-in network cards (Realtek) and two on an external pci device (Broadcom).
And if I output ip a, I get the following picture:
And I have no idea where all the other devices come from.
In the proxmox logs after updating to version 8, messages like this started to pop up:
In general, I would like to set up the entire network environment from scratch, with a full understanding of the matter, so that there would be no problems in the future.
Oh, by the way, for some reason only one device in the pve gui is displayed with the type "network device" - this is also not very clear to me, when there are physically 4 of them.

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!
