Issue

How do I configure my ISA server to work with PASSPORT Web to Host to allow my remote users to connect to our host system using only port 80 rather than opening port 23 to the public?

Solution

This can be done by configuring your ISA server to do TCP port redirection. Review the information from the link below for detailed instructions:
