We finally got our server to start and load everything, but we can not connect to the internet. It worked about 2 weeks ago, but the server stopped running. After several restarts, it finally started again and got us to a root prompt. eth0 is up, but no internet.
I can not copy and paste from the server monitor, so I can not post any codes here. ifconfig comes up with eth0 and l0, and both have the inet IP, Broadcast IP, netmask, etc listed.2 servers are hooked to a router, then router to modem. The other server works fine over the internet. What should we look for? It must be IP configuration right?

Please help

I did not find the right solution from the internet.
