How to Port Forward QSee QSD2216C16-250 on the Arris TM502b

Having trouble forwarding ports on the Arris TM502b?

If you are having trouble with this guide, then perhaps PFConfig may be your solution. PFConfig is a software tool that will automatically forward ports for your router to save you time and hassle.

Before we can forward ports to your DVR, we need to change some settings in your DVR. Use your remote control to enter your DVR's System Setup menu.

Select the Network option from the System Setup menu.

Write down the number that is in the IP ADDR, Gateway, and Sub Net sections. Change the IP Mode to STATIC IP. Do not change the Gateway and Sub Net settings. We are going to create static ip address for your DVR and use it from now on. The IP address in the picture above is The 111 portion of that ip address is called the last octet. Each octet of an ip address ranges from 1 to 254. If you have an ip address where the last octet is closer to 1 than 254, add 50 to the last octet and set the IP ADDR to that. If you have an ip address that is closer to 254 than 1, subtract 50 from that last octet and set the IP ADDR to that. Save the settings and get out of your DVR's setup. In this example the last octet was 111. So the new octet in this example would be 161, and the ip address in this example would be Do not use those values they are just an example.

You will need to restart your DVR before those settings will take effect.

Remember what you set the IP ADDR to. You will need to tell your router what IP Address to forward those ports to. Since you want to forward ports to your DVR you will need your DVR's IP address.

We've already taken care of setting up the static ip address in the guide below so you don't need to worry about that part. Just enter your DVR's static ip address that we just setup in to the box requesting your computer's ip address bellow. You won't really be forwarding ports to your computer, but you will be forwarding them to your DVR. Everything else is the same, just keep in mind that the ports will end up being forwarded to your DVR and not your computer.
