Proxy Port configured is not used in client traffic

Hi,

I am configuring the on premise Check Point 6200B as a Transparent Proxy for outbound traffic from clients. See attached screenshot. I have changed the default port 8080 to 9999 since the port 8080 was already in use by an internal application which gave a conflict.

On the Windows Test client i have no proxy configured since we are looking to test the Transparent option.

My question: How is the Port 9999 (or 8080 if you keep the default) being used in the proxy traffic between the client and the gateway?

I don't see that port 9999 in the Wireshark captures when browsing the internet. The proxy connection itself works OK which i can check by examening the certificate in the client browser. Shows the gateway CERT.

Transparent proxy only processes HTTP traffic on the specified ports (8080, 9999, or whatever).
This is described here: https://support.checkpoint.com/results/sk/sk110013
What is your exact goal in using Transparent Proxy here?
