We need to enable ports 8443 and 8445 on our ISA server. We can't see where to do this and because we have very basic knowledge are worried about making changes or using tools that might screw up our configuration. can anyone help.

    By default ISA Server will not allow Web Proxy connections using a non standard port. You will have to create a "Proxy Tunnel Port Range" to tell ISA server to allow web proxy traffic through this port. (By default Web Proxy filter will only allow 80 (HTTP), 443 (HTTPS) and 563 (NTP) throught the proxy filter)

    You can create a new tunnel port range under

    (just use the existing entries there as example; I am away from my ISA Server and I don't remember the exact syntax)

    You can also use "ISA Server tunnel port tool" from to create custom port ranges. Run the script from your ISA Server and follow the instructions to create the new port bindings. Once that is done, create a custom protocol with TCP 8080 outgoing and add it to your Allow Internet access rule.
