    Install the Microsoft Firewall Client and open the ports on the ISA server where needed.

        If you don't want to open the ports you needed then it's done.
        I don't know you're physical network setup but if you're going to bypass you're own firewall you'll create a security breach.

          You can also configure putty to do ssh tunneling. That way you just tunnel through a port that is already allowed the the ISA rule set and you don't have to worry about punching additional holes in the firewall.
