Trendnet TDM-C400 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 Trendnet TDM-C400 router.
- Navigate to the port forwarding section.
- Click the Services button.
- Select NAT Rule Entry in the drop down.
- Click the Add button.
- Create a port forward entry.
While these steps might seem difficult at first, we will walk you through each step for your Trendnet TDM-C400 router.
We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.
When you use Network Utilities you get your port forwarded right now!
It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.
- Recommended - Our free Static IP Setter will set up a static IP address for you.
- Another way to get a permanent IP address is to set up a DHCP reservation.
- Or, manually create a static ip address with our Static IP Guides.
This step is important because you want a permanent IP address in your device. If you do not set up a permanent IP address in your device, then when you device reboots it may get a new IP address.
Now we are going to login to your Trendnet TDM-C400 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.
Open up your web browser and find the address bar. It should look something like this:
Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.
The default Trendnet TDM-C400 IP Address is: 192.168.1.254
After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:
Click the Services button near the top of the page.
Select NAT Rule Entry from the NAT Options drop down box.

- Browsing our List of Games
- Check out our our List of Games by Genre
- See our List of all Applications
In the Rule Flavor dropdown box select RDR.
Put a number that has not yet been in the Rule ID box.
Make sure that IF Name is set to All.
The protocol that you want to forward is selected from the Protocol box.
You need to enter the IP address that you are forwarding ports to in the Local Address From and Local Address To box. It's possible for this to be either the IP address of your computer or any other IP address on your network that you want ports forwarded to.
Leave Global Address From and Global Address To set to 192.168.1.254.
Leave Destination Port From, Destination Port To and Local Port set to Any Other Port.
If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Local Port box and the highest number of that range into the Destination Port From box. If you are only forwarding a single port number then enter that number into both the Local Port and the Destination Port From boxes.
Click the Submit button when you are all done.
Click the Close button near the bottom of the page.
Click the IP Filter link near the top of the page.
Select Low from the Security Level drop down box.
Select Accept from the Public Default Action, Private Default Action and DMZ Default Action drop down box.

Click the Admin button near the top of the page.
You should now see a new menu. In this new menu, click Commit & Reboot.
Click the Commit button near the bottom of the page.
Click the Reboot button near the bottom of the page.
Your ports should now be open. It is time to test them.
