I read just about every thread here regarding this issue, and I can't find out what I'm doing wrong. I'm trying to publish a web site, as well as TSAC.
I'm running an IIS 5.0 on Win 2k sp3. This is behind an ISA Box.
Before having ISA on the network, everything worked fine. As soon as ISA is up and running, I get the 403 error when trying to access the site EXTERNALLY.
I went through the articles by Tom on how to publish a site. In the properties of my ISA server, I configured the 'Incoming Listener' to listen on my external interface, at port 80, and I also enabled WPAD.
I have my Destination Set as www.rk-ane.com, which points to my web server. I have created the Web Publishing Rule, which points to the specified destination set, my internal server name, and port 80. I created a Protocol rule to allow for incoming HTTP access. I even tried creating Packet Filters that allow HTTP over port 80 in, but it still doesn't work.
I tried Microsoft's solution which recommended I change from port 80 to another port, but it still didn't work.
