First off, it might be useful to explain that my local network setup is:

[Internet] <---> [192.168.1.1] <---> [10.10.10.1] <---> [Computer]

so, the router at 10.10.10.1 is the computer's gateway and router 192.168.1.1 handles DNS requests.

I installed Ubuntu 12.04 server on the computer in question, but I can't seem to get the ethernet connection working properly. Here's the info that I would think would be useful:

Any advice would be greatly appreciated, and let me know if there's any useful info that I left out.

PS: I did make sure that address 10.10.10.2 was reserved on the router for the server's MAC address
