I'm setting up my firewall and am having trouble with it. I think it is because I do not understand how to set up the internal (trusted) and external (untrusted) interfaces, specifically how to let the internal interface talk to the external interface.
Can anyone give me EXAMPLES of the values to input for the internal and external interfaces?
What I have so far is that the IP Address of my internal interface is 192.168.42.7. And so all the PCs in my office have the default gateway set to 192.168.42.7, and I can ping the internal interface just fine. Problem is how to let my PCs communicate with the external interface?
