This page will show you how to setup a port forward on the Buffalo DD-WRT 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.

NordVPN faster than ever deal!

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.

Other Buffalo DD-WRT Guides

This is the port forwarding guide for the Buffalo DD-WRT v24. We also have the following guides for the same router:

Configure your Computer to Have a Static IP Address

Port forwarding the Buffalo DD-WRT to your computer can be more reliable if you first configure a static IP address on your computer. We have instructions to setup a static IP address for Windows 7, Windows 8, and a variety of other devices on our Static IP Address Settings page.

Please note that while setting up a static IP address on your computer is optional, it is still a very good idea to go ahead and do it. In the long run it will make your port forward much more reliable.
