RE: [FW1] NAT Question



You can do a couple of things.
Hosts files with the internal IP address
Internal DNS server with the internal IP address of the server.

Subject: [FW1] NAT Question


Hello all,

I'm helping a company upgrade their CheckPoint firewall.  They have an
Exchange server on their internal network running Outlook Web Access (OWA).
Though they have plans to move it to their DMZ, for now they have to keep it
on their internal network.  The firewall is performing address translation
on the server.  The outside world and dmz access it fine.  However, the
internal hosts are having trouble accessing it.  The DNS server the client
is using is returning the valid (translated) address, not the actual
(internal)address.  If I traceroute the translated address, the path looks
correct - client>router>firewall>router>server.  However, they are not able
to access the server via http.  If I have them type in the actual address in
the URL, they have no problem.
Any ideas?
Thanks!
Sudhir
