3com 3c510 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 3com 3c510 router.
  3. Navigate to the port forwarding section.
    • Click the Virtual Server link.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your 3com 3c510 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.

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.

Step 2

Now we are going to login to your 3com 3c510 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 3com 3c510 IP Address is: 192.168.2.1

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

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:

Enter the port to forward into the Service Port box.

Enter the IP address that you want to forward these ports to in the Server IP box. You can enter either the IP address of your computer or the IP address of another computer or device on your network.

Verify that you have the Enable checkbox checked.

When you are finished, click the Save button at the bottom of your screen.

Test if Your Ports are Open

Now that you have forwarded ports on the 3com 3c510 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.
