Known problems updating zywall firmware
Remember a router is a hardware based firewall, it blocks incoming connections except those allowed through by the port forwarding rules.In cases like this the only real reason to have a software based firewall installed is to block programs from connecting to the net.On this page I will go over the most common problems I find when helping people get their port forwarding working and how to fix them.If you would like to know more about what port forwarding is you can check out my page "Port Forwarding in a Nutshell" When testing your port forwarding to your computer make sure to use my Port tester program and not an online port tester.So now you know to check and see if your router has any firewall options that might be blocking the port forwarding rules.Here is an example from a Zyxel Router and its firewall options. Here is an example from a rather Common Router and its firewall options.I log into my PS3, go to the network status and find what IP it has. I will not use the IP of my computer or the IP of the server I want to connect to.
As you can see if it is set any higher than minimum security that all the inbound policies (the port forwarding rules) will be rejected and port forwarding wont work.Other times people may want to make a port forwarding rule for their PS3 or Xbox and put the wrong IP in as well.To make sure the port forwarding rule is working correctly, the IP address of the rule should point to the computer, or machine, you want the connection to go to.So the user had to dig in and get them removed before port forwarding would even work.For a user who doesn't understand how or what a firewall is used for, they should not have one installed if they are behind a router anyways.
