Hi Mustafa, You only need to bind the certificate to the Web listener. The cert on the bridging tab is used for user certificate authentication so that the Web Proxy service can authenticate with the Web site. However, must OWA Web sites do not require user cert auth, just machine auth, although I use it for high sec environments with ISA firewall in packet filter only (like PIX) protected environment, since I figure the packet filter provides almost no useful sec for my applications. If you're using only ISA firewalls, then you don't even need to consider this option. Thanks!

I exported it to a file and then imported it to ISA server. I need this certificate because of SSL connection between ISA server and Web server. - I created a second certificate (also Web Server certificate template) on ISA server. I need this certificate baceuse of SSL conncetion between clients and ISA server. That is the SSL Briding with two different SSL connections (Clients to ISA and ISA to Web server). Or not?
