Ex2K3 access through firewall

Scenario: Ex2K3 on W2K3 on firewall DMZ. The users are wan and lan based.
Clients use Outlook 2000, XP, & 2003 running on W2K or WinXP. Wan clients
need access to Ex2K3 on DMZ.

What ports do I need to open on the firewall in order for the various
Outlook clients running on the two different OSs to have access to Ex2K3 in
order to connect as Exchange corp clients? I've seen several similar posts
that refer to documents on RPC over HTTP, but then the article says this is a
WinXP feature ("RPC over HTTP on the client-side is a Windows XP feature");
so this config would not help the W2K OS clients.

Thanks, Mike Lawson
