I have Z490 board with RTL8125B LAN controller which was not being detected by Proxmox installation so I ordered a TPLink NIC from amazon. Installation finished fine but I noticed that during installation Proxmox actually picked up RTL8125B as my management interface.

Also I noticed that it chose 192.168.100.1 as my default gateway and that's incorrect. Do I need to disable my internal RTL8125B LAN for this to work? After installation, I cant ping/access my server
 
Realtek NICs and Linux are usually a bit of a problem due to driver issues.

What does the /etc/network/interfaces file look like?
 
Yeah, it was dual NIC issue indeed. I went to bios and disabled onboard LAN controller and then it worked just fine. Thank you.
