Fixing Network Bridge & New NIC

[emcdch]

Hello!

I have an issue that I am way over my head on. I am inexperienced with Linux network bridges and I somehow managed to toast my one existing Linux bridge. When I installed my IBM 49Y4241 4-port NIC, it reset my network settings and I had to manually change the /etc/network/interfaces file to get any network back to my proxmox environment. However, at the moment, the onboard NIC is labeled as an unknown network device and the original network bridge no longer works. How would I go about resetting my network settings and building a bridges for one WAN port (built-in NIC) and 4 LAN ports (IBM 49Y4241 NIC)? Here is a screen shot of my current host network config.

Thanks!

Hey,

what is the output of cat /etc/network/interfaces and ip a?
