Welcome to the forums.

Have a look in the wiki for split domain DNS.

yes indeedy, split horizon dns always causes some confusion. make sure your rhel4 box is resolving on the internal network - look in /etc/resolv.conf and see if the nameserver is on 192.168 or if its pointing to something external.

make sure your /etc/hosts file is setup correctly too.
