Hi Marvin, If you're using DDNS (TZO etc) the public address on the DSL NAT device will accept the incoming requests for the OWA site and will forward them to the ISA firewall's Incoming Web Requests Listener. So, the Web Publishing Rule just needs to be configured to accept incoming connection requests for the FQDN the remote users use to access the site. Do you think we need an article on ISAserver.org or in the book on how to do this? Is this a common scenario? (I guess I answered my own question, since both you and I use this type of setup :-)) Thanks!

The external interface is a private IP of 192.168.1.x. Question: how to publish OWA and multiple servers over a DSL connection? Problem: web server is currently published as listener for external IP. This means ISA doesn't see any more external IP addresses. I can access web sites externally. Problem: ISA didn't see the external interface so I configured it to listen on the IP of the internal interface. I'm still unable to access the OWA externally. Problem: unable to publish mail server because ISA doesn't see any external IP addresses. #%@#!!! Qestion: What must I do to enable ISA to allow me to publish multiple servers on this external interface? Any responses are appreciated.
