That won't work. ISA will allocate dynamic ports for FW client connections. You're better off to swap the ISA and Checkpoint.

I have created the following rule on the checkpoint firewall: >From Firewall Client To Isa Server Allow Port 1745. However when I try to browse the internet from the machine where i have installed the firewall client, I am unable to do so. From netstat i have been able to gather that the firewall client connects to the isa server on some dynamic ports apart from 1745. How do i configure the firewall client to connect to the isa server on some specific ports? Any help or suggestions in this direction would be helpful.
