Your PIX config should look something like this.

(A lot is cut out, this is the stuff for port forwarding.

no fixup protocol smtp 25
access-list acl_out permit tcp any host 204.50.X.X eq 3389
access-list acl_out permit tcp any host 204.50.X.X eq smtp
access-list acl_out permit tcp any host 204.50.X.X eq 443

I had that port opened, but could not connect. I use a PIX, so it is a
statefull firewall. I wonder if that is stopping it. Is 443 the only port
I need to open?

Ideally port 443 so you can run OWA over SSL

No, both locations are not SBS.  The only thing is that I do not want SBS to 
act as a proxy server.  I guess I could just use one NIC and let my PIX do 
the firewall function.  I just wanted an extra layer of security.  If I just 
use an internal NIC, what do I need to forward through the firewall to be 
able to use OWA?

Christopher
You should absolutely visit www.smallbizserver.net and check out the 
information on configurations there
ISA is designed to protect the internal network by acting as a firewall on 
the external nic.   The external facing nic (in your case the one that would 
connect to your PIX) must be a on different subnet from your internal nic
I'm not sure why you considering adding another level of complexity to your 
setup.  You have a hardware firewall protecting each internal network.  You 
could of course increase the protection by adding ISA.  But you need to do a 
little studying and you would be making some big changes to your existing 
networks on both and you could be looking at some down time.
Are both locations SBS ?

I am tiring to setup a SIBS with two nic cards.  The IP address scheme 
inside the network is 192.168.1.x at the first site and 192.168.5.x at the 
second site.  We have a VPN that connects the two.  Our PIX firewall handles 
the VPN. (PIX to PIX)  I would like to get an inside and an outside nic 
going.  I would like to use private IPs for both of them and forward traffic 
to the outside nic to handle clients outside the network.  Both sites will 
use the inside nic for Exchange and DC.  Can you tell me how to set the nic 
cards on the server and what to use on the clients?  Is there a better way 
of doing this.  I do not want the external nic to have a public IP address. 
Could I use an IP address in the 192.168.1.x subnet (same subnet as my 
inside nic at site one)? I am going to set ISA server up once I get this 
problem taken care of..although, I do not want my clients to use ISA as a 
proxy server.  Also, once I install ISA server, what do I need to do to make 
sure replication can occur between DCs.  Is it possible to only implement 
ISA on the outside nic?
Thanks,
