Raptor NT Firewall

[pabs]

Our setup is such that we have branch offices that connect to the main office via ISDN lines through our Raptor NT Firewall. Our Exchange Server 5.5 sits behind the firewall and I was wondering what to open up on the Firewall so that branches can connect to Exchange and have the same functionality as users at our main office?

Any help by this novice would be greatly appreciated.

Thank you.

You have to open up 135 and then another >1024 port that you specify. You also have to make some registry changes to both the Exchange server to force these ports and to the Oulook clients that will be connecting through your firewall. The articles below describe what to do.
