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 is the fastest VPN!

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.

What is the LAN IP Address of a Router

The LAN IP Address of a router is also known as its internal IP address. It is also the IP address that you connect to when you want to configure your router. It is only useful from inside your network and has no use from the Internet side.

Routers have 2 IP addresses: an internal ip address and an external ip address. The external IP address is assigned to you by your Internet Service Provider, or ISP, and is generally not something that you can change. The internal IP address is set to a default value at the factory but can be changed if you want.

Common internal IP addresses for routers are:

  • 192.168.0.1
  • 192.168.1.1
  • 10.0.0.1

It is generally a good idea to make the last number of your router's internal IP address a '1', as in 192.168.0.1 or 10.0.0.1. This is not necessary, but many people do it and it makes it a bit easier to remember which IP address is assigned to your router. If you want to change the internal IP address of your router, this guide shows you how.

Possible Problems when Changing your LAN IP Address

When you change your LAN IP Address you are making a fundamental change to how your network functions and all computers on your network will be affected. You will lose your Internet connection when you apply these changes. Your router may reboot and require a couple of minutes to start responding again.

Also note that some computers may need to be rebooted after you make this change before they can talk to the router or on the Internet again.
