Questions related to RHEL 3 should go to taroon-list, not redhat-list.

This is a really strange setup...

The webserver should have separate IP addresses for the internal and
external interfaces.  The nameserver then needs to resolve the name to
the right one, answering with the internal interface address for your
internal hosts, and with the external interface address for your
external hosts.  Bind 9 has a split personality mode that allows you to
do things like this.

My guess is that your nameserver is returning the external IP address to
your internal clients.  You then do not have a route to that subnet.
