Easiest Way to Forward Ports on the Comtrend CT-536 Router
Comtrend CT-536 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.
The basic process to open a port is:
- Setup a static IP address on either your computer or device that you want to forward a port to.
- Login to your Comtrend CT-536 router.
- Navigate to the port forwarding section.
- Click the Advanced Setup link.
- Click on NAT.
- Click on Virtual Servers.
- Click the Add link.
- Create a port forward entry.

Open up your web browser and find the address bar. It should look something like this:
In the picture above the address bar has 192.168.1.1 in it. Just replace all of that with the IP address of your Comtrend CT-536 router. Your router's IP address can also be refered to as your computer's default gateway.
By default the IP address is set to: 192.168.1.1
After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Select the Custom Service radio button.
Make up a name to put in the following box. The name does not have any effect on the functionality of the forward, it's simply there so you can know why it was created.
Enter the IP address of the device that you want to forward ports to into the Server IP Address box. This can be either the IP address of your computer or the IP address of another device on your network.
If you are forwarding a single port, enter that port number into the External Port Start, External Port End, Internal Port Start and Internal Port End boxes. If you are forwarding a range of ports, enter the lowest number of the range into the External Port Start and Internal Port Start boxes. Then enter the highest number of the range into the External Port End and Internal Port End boxes.
Use the Protocol dropdown box to select the protocol type of the ports you are forwarding.
After you are done click the Save / Apply button.
Your ports should now be open. It is time to test them.
