Published website not reachable from the internal network

Our published websites (several different domains) aren´t reachable
from the internal network. We are running these websites on a internal
webserver, that is published on the isa server 2004 for external
access.

The whole world can access those sites, without any problem.... only
the computers on the internal network can´t using the normal domain
names of those websites.

I figured out that the internet router (an Alcatel Speedtouch) does
everything fine and routes the trafic to the external interface of the
server. After this, ISA denies the http traffic.

Any ideas?
