Hello, Currently, I'm running ISA 2006 Std. Ed on a 3-leg perimeter network setup. I wanted to publish a web server. We are running on cable with IP Address being assigned dynamically. Cable Co. cannot give us static IP add. Can I still publish my web server even though my external IP add changes every 3 days? Also, can I allow a certain application (say 123apps.exe) to access the web? Like IE, when you open - it goes to the default homepage of IE settings. This application is accessing a particular server over the web and we submit critical info thru that server. This happen when I install FWClient. Without/disabling FWC, the application works fine. Is there something I missed? Thanks, Art
