Either this diagram is wrong, or you have it setup in a strange manner.

Shouldn't the router be facing the 'net, and the computer/server connected to the switch? Then the switch in turn connected to the router so the machines can hit the 'net...?

So what have you tried? Is the LAN OK? Can you ping machines on the LAN? What have you tried for WAN access? DNS? Ping? Anything?
