Thankfully the routers that have the extra firewall options come with good information on the page about which setting you should use to allow port forwarding to work.Normally you can just turn off the firewall or just put it at its minimum setting. A router is a hardware based firewall already, the firewall options in the router are simply more options to better control things if needed.Some users have put internet IP's in or just the wrong IP all together (Such as putting their computers IP in when they want the IP from their Xbox).So lets say I want to make a port forwarding rule that sends an incoming connection to my PS3.So when the port tester program says the ports are open you can count that they are :-)" The port tester is only for testing to your computer, not to other devices, because it has to open the port on the system to listen for a connection. Thankfully it is easy to get port forwarding if this is happening.

So the firewall drivers where left behind and blocked all incoming connections.

As for this example you will see the WAN (Internet) to LAN (Your Computer) is set to block. As for this example the SPI options blocks all the port forwarding. Routers differ in their firewall rules and settings.

Make sure to check for any firewall settings in your router to see if anything is set to block incoming connections.

I have also added this tool to the Simple Port Forwarding program under the tools menu) As you can see by this example this routers internet IP is a local address, this means we are behind another router. Find the status page that shows the WAN/Internet IP address and write it down. While other routers let you put the whole IP in (Some users accidentaly put the internet IP instead of the Local IP in).

So in this case I logged into this router using and to log into the other router I would use (The gateway address in the picture) . People can get confused on what IP address they should put in.
