Setting up a apache server

Hi there,



I'm trying to set up a debian web server (apache 2), which is running behind
a NAT router. Every thing is working fine. Things like SSH and the standard
apache greeting page.



But when I'm going to make things a bit more complicate, like installing
MAMBO server. Strange things are happening. Everything is working fine from
inside. But when I'm connecting from the outside world, only text is coming
up. Almost every picture isn't showing up. And if you watch de status bar of
the browser, you see it's trying to download the pictures from the internal
IP-address (192.168.1.X). So it's exposing my internal IP address.



After reading tons of doc's en trying different thing (DMZ, port forwarding,
virtual hosts, etc etc) I'm a bit lost.



So any help to guide me in the right direction is much appreciated!
