Linux firewall and web exchange server

SSBN · 06-21-2003, 11:02 PM

I have an exchange server behind a smoothwall gpl1 box. Gpl one was before Linux was using iptables. I have all the internal mail clients working. The exchange server can send and receive mail. But from the outside I can’t get to the exchange web access. I know it is working because when I had ISA as the firewall it worked fine. What ports do I have to forward to get web access working thanks?

I would expect just port 80. But knowing MS there could be 100 others. Try just port 80 and if it doesn't work then look at the firewall log for rejected connection attempts and use those as the basis for forwarding more ports.
