I am pretty familar with basic port forwarding, but my current router has some pretty interesting options, and to be honest, I have no idea what they mean. Here is what my screen looks like: I AM USING A Ambit U10C019 Wireless Cable Modem Router What I want is to open ports 6112 - 6118. However, I don't know what "public interface IP" means, or what I should set for "internal IP"? How do I find the "public interface ip"? If anyone can help me with these settings I would definitely appreciate it.
