Routing Problem

I have a routing problem with my linux box which runs SuSE 9 ES. The computer is located in my DMZ. When I try to login via SSH or send an HTTP request it answers very slowly. When the PC was still in the intranet it worked just fine.
I have no clue what could be wrong.

Wow, Pete. IP routing is this century's answer to alchemy. Dark magic. There's a lot that can go wrong and tracking the problem down can be difficult. I had a problem with a server that would choke on large uploads (> 2 meg). Turned out my DSL modem had a poorly configured routing table. You can imagine the time I spent with my ISP's tech support trying to convince them there was a problem.
But enough about me. One thing you want to be sure is that you are connecting to the right IP. You have internal and external IP's to your server, right? The external one will be slower (in my case, DSL vs. 100mbps LAN, much slower). You can use utilities like traceroute to see exactly where your packets are going.
Good luck. Resolving this problem is going to take some detective work.
