If you want the connection to be seemless from the second ip in server1 you will need to do a DNAT to the second ip. If DNAT is out of the question, then you will just need to make sure that you have a route to the server2 in the server1 and activate forwarding to that ip... but that will only work if you set server 1 as a literal gateway to server 2 ( useless ). I might advice you to figure out why your server doesn't go outside its network correctly, might be something as simple as domain or route errors. -- Guillermo A.
