Ok, I also tried as per Tom Shinder's Tutorial. But still not working. In my external dns server I have mx record wich pointing to external ip of ISA server(secondary IP.). One CNAME(Alias entry ) pointing to same external Ip address of ISA server. Like <Exchange server name> host <external IP> Mail exchanger(MX) <exchange server name.> Exchange CNAME <exchange servername>.domain.com Is this alright. I also configured incoming webrequest to port 8080 (80 also ) of the external Ip address of ISA server. I f I try to open exchange.domain.com from browser it directing to the external ip but immediately page cannot be displayed message is coming. But OWA is working locally with http://internalip/exchange Any hints?
