I am currently using ISA 2006 to publish OWA 2007. I want to add an additional listener so some of our users can authenicate with RSA. I created a new listener for RSA authentication but when I create the firewall policy rule using this listener I get an error that says "A Web listener specifying the same port and similar IP addresses is already used by rule "Exch07 OWA". The port and IP addresses specified in a Web listener cannot overlap with the IP addresses and ports specified in another Web listener already used in a different rule.". Is it possible to publish OWA with and without RSA on the same ISA 2006 server? If so, how would I do this?

Add another IP address or port number. Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Use another IP address, but that leads to problems with autodiscover unless you also use a second namespace. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
