Basic troubleshooting will be required, so if you can get 
traceroute installed on the server, that would help.

Can you find any interesting details when you traceroute to 
the server from the LAN and Internet? Is the path taken the 
same with both tests?

Can you ping the server from its closest upstream router? 
How about the reverse; can you ping the router - acting as 
the server's default gateway - from the server?

Does the upstream router have an ARP entry toward the 
server, in its ARP table?

There is very little information to go on, hence the 
otherwise open-ended questions :-\.
