3com 3CRWER100-75 Port Forwarding Instructions

This page will show you how to setup a port forward on the 3com 3CRWER100-75 router.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

• Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
• Make sure that your VPN provider has lots of exit nodes all around the world.
• Check that your VPN will not affect your speed.
• Verify that your VPN provider uses WireGuard as the underlying protocol.
• Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

You should now be on the Virtual Server page of the 3Com 3CRWER100-75. In the first box under the heading of Application Name enter the name of the program that you are forwarding the ports for. It is not really important what you enter here, but we highly recommend entering something that will help you to remember why you are forwarding these ports.

In the next box to the right, if you are forwarding a single port, enter that port number in both the Start~ and End Port boxes. If you are forwarding a range of ports, enter the lowest number of the range in the box to the left labeled Start~ and the highest port number of the range in the box to the right labeled End Port.

Next, using the drop down menu, select the Protocol that you wish to use when forwarding these ports.

Now we have the To IP Address box. Enter the IP Address you are forwarding these ports to in this box. For example, if you are forwarding ports to run a particular program on your computer, be sure and use that computer's IP Address here.

Finally, place a check mark in the Enabled box.

That's it! Click the box labeled Save and you are finished!
