I'm new to ISA 2004, and need to publish multiple websites behind it. I have run through the publish wizards, and for some reason I'm not able to get to either website from outside of my network. Current setup looks like:
- ISA sits behind existing firewall as part of private network (not the best scenario, but..)
- Existing firewall is NATing all incoming HTTP and HTTPS traffic to ISA
- Used ISA publishing wizards to publish websites (one is Exchange 2003 w/ OWA and Moble Sync, etc. Have turned off Forms authentication, and have published both the web site for OWA and the mail server itself). Second server listens on port 80 as well. This one requires orginal header to function correctly (server.domain.com).
- Internal DNS has been configured, and both sites work fine behind our firewall. External DNS has been setup, and traffic gets to external firewall and then to ISA.
Any ideas, suggestions, etc. would be greatly appreciated.
