If you upgrade to Exchange 2003 you can use RPC/HTTPs to overcome this.
 
On Exchange 2000 you are pretty much limited to either opening the
ports, or using ISA to public Exchange.

Subject: [exchangelist] Connectivity through PIX firewall


http://www.MSExchange.org/

Hi all,
 
i am trying to implement a new exchnage environment and have some
questions regarding connection from outlook clients to exchnage 2000
cluster though a firewall.
we have opened up ports 25, 135, and 435 to the exchnage server from
clients but what seems to happen is that exchnage picks random ports
when connecting to the information store and directory services. We dont
want to open the firewall for hundreds of these port numbers( ie 5000,
5421 etc)  and was wondering of we could use something like IP Sec to
determine connectivity. Has anyone come across this issue? we have tried
to assign these staticaly but does not work with exchnage in a clustered
environment.
 
any help will be appreciated.
 
 
many thanks
 
Bindesh Patel.
