Fastest SMC SMCD3GN2-RES Router Port Forwarding Instructions

SMC SMCD3GN2-RES 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:

  1. Setup a static IP address on either your computer or device that you want to forward a port to.
  2. Login to your SMC SMCD3GN2-RES router.
  3. Navigate to the port forwarding section.
    • Click the NAT link.
    • Click on Port Forwarding.
    • Click the Customer Defined Service Add button.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your SMC SMCD3GN2-RES 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!

Step 1

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 program will setup a static IP address for you.
  • Or follow our Static IP Address guides to setup a static IP address.

After setting up a static ip address on your devices you need to login to your router.

Step 2

Now we are going to login to your SMC SMCD3GN2-RES 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:


192.168.0.1

In the picture above the address bar has 192.168.0.1 in it. Just replace all of that with the IP address of your SMC SMCD3GN2-RES 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: 192.168.0.1

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

SMC SMCD3GN2-RES

You should see a box prompting you for your username and password.

  • The Default SMC SMCD3GN2-RES Router Username is: cusadmin
  • The Default SMC SMCD3GN2-RES Router Password is: password

Enter your username and password, and then click the Login button to log in to your SMC SMCD3GN2-RES router.

SMC Usernames and Passwords

If your username and password do not work then please visit our Default SMC Router Passwords page.

If you still can't login to your router because you forgot your SMC SMCD3GN2-RES router username and password, use our How to Reset a Router Password guide to set your SMC SMCD3GN2-RES router back to its factory settings.

Step 3

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:

SMC SMCD3GN2-RES

Step 4

Here are the ports to forward for Xbox Live:

TCP Ports:3074
UDP Ports:3074

If you are looking for the ports for a different application you can find it by either:

Put a name for this forward in the Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you.

Use the Type dropdown box to select the protocol type of the ports you are forwarding.

You need to enter the IP address that you are forwarding ports to in the LAN Server IP 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.

In the Remote IPs dropdown box select Any.

Use the Public IP Ports dropdown box to select Single Port or Port Range.

If you are just forwarding a single port number then you can simply enter that same number into both the Private Ports,Start Public Port and the End Public Port boxes. If you are forwarding a range of ports, usually separated by a hyphen, then you need to enter the lowest number of that range into the Private Ports,Start Public Port box and then enter highest number into the End Public Port box.

When you are finished, click the Apply button.

Your ports should now be open. It is time to test them.

Test if Your Ports are Open

Now that you have forwarded ports on the SMC SMCD3GN2-RES you should test to see if your ports are forwarded correctly.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.
