Hi folks, I have a question for you. My ISA server is behind a Checkpoint Firewall 4.1. Its is a brand new server installed with windows 2000 sp2 , one interface connected to the internet, the other connected to the firewall 1. Due to ?security? reason we had to use checkpoint. When a client try to reach the web proxy, the request goes to the ISA using Http port 80 and it?s ok but when the ISA replies to the client it uses a ?random? port. Our checkpoint admin doesn?t want to open all the port, so is there a way to force the web proxy to use a ?fixed? port when replying to a client ? A proxy server 2.0 does that but I can?t find any documents, nor on checkpoint site nor on Ms site. Can you help ?
