internal DNAT not working

hi all,

we have setup a DNAT to a DMZ web server which works, when people are trying to access it externally ie WAN, when they type in the FQDN it resolves to the correct external ip and they can view the website

we have one internal LAN network that has all outbound access all ports ie internet access, and there DNS for that FQDN is pointing to the correct external ip, so you would had thought as they have internet access and there DNS is pointing to the correct external ip, it should work but when they type in the FQDN on there machine, the webpage just times out

pinging/tracerout to the FQDN points them to the correct external ip and they get no hops obviously as its going out the FW and straight back in so its just one hop which is the external ip

any reason why this isnt working?

thanks,

rob
