Why Belkin Router Port Forwarding Stops Working?

Hi all, I am having a constant problem with my Belkin router. I need to access one of my home devices outside my home network. So I need to setup port forwarding. I did this and I am able to access the device fine. But, it will not stick. I can only access for 20 minutes, then it is blocked. I go back into the router configuration and it shows the port forwarding is active. I won't make any changes but when I click on Apply button it restarts and then port forwarding works fine again. The router is a Belkin F5D7234-4 v5 Wireless G. I have CenturyLink DSL with a ZyXEL 660R modem. The modem is in Routing mode. I originally setup the router to be in the DMZ of my modem. Then I removed the DMZ and added the ports I want to forward on the modem to point to the router. Either way, I am able to access the device properly for about 20 minutes. I can't figure out why it is happening. Please help me.

Belkin Router Port Forwarding not Working -

Belkin Port forwarding allows external devices to pass through your router's firewall for services such as a web server (Port 80), FTP server (Port 21), gaming or any other designated applications. This article will show you how to setup port forwarding on a Belkin router.

Before proceeding, make sure that you have the following:

  • The IP Address of the computer or device to have the port forwarded to.
  • The port numbers to be used and whether they are TCP or UDP ports.
  • The router connected to the computer using an Ethernet cable.

To enable Belkin port forwarding, follow these steps:-

Step 1: Open your web browser and enter router’s IP address ( by default) in the address bar. Enter username your router password (the default password is blank).

Step 2: Navigate to Firewall > Virtual Servers.

Step 3: Check Enable.

  • In the Description column, enter a description of your network device (e.g. INSTEON Camera 1)
  • In “Inbound port” enter camera’s port number.
  • Next, choose the “Type” you want to use. (For INSTEON cameras we will use TCP or Both)
  • Enter the Camera’s IP address in “Private IP Address”
  • In “Private port” enter camera’s port number.
  • Repeat step 5 for any more ports you want to forward.
  • Click on “Apply Changes”.
