Forwarding Ports for Defender 21152 on Your Router.

When you use a Defender 21152 DVR you may need to forward ports in your router. Forwarding ports is used to allow incoming connection requests from the internet to a Defender 21152 DVR.

By default routers do not allow incoming network requests. By forwarding ports you can work around this limitation.

Before you can forward a port you need to know the following things:

• Your router's internal IP address.
• The IP address of your DVR.
• A list of TCP and UDP ports that need to be forwarded.

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.
