Help with firewall rules.

[dpatton]

Currently, I am trying to simulate a customers network here before we send a linux appliance out. I have blocked all traffic except for 443, and so far the appliance connects and works correctly(this is good).

Is there a way I can use firewall rules to force all traffic through port 3128? and will https go through 3128 if the linux appliance  has an https_proxy statement in its /etc/environment file?

Thanks in advance.

To allow specific ports through to any particular destination, you can create this rule in NAT (Network Address Translation).  Just specify the ports in the outbound tab and select LAN subnet.
