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.

Find Your Huawei HG8121H Router IP Address
Before you can log in to your Huawei HG8121H router, you need to figure out it's internal IP address.
| Known HG8121H IP Addresses |

| 192.168.100.1 |
You may have to try using a few different IP addresses from the list above. Just pick one and then follow the rest of this guide.
If the IP address you picked does not seem to work, then simply try a different one. It should be completely harmless to try different IP addresses.
If you try all of the above IP addresses and still cannot find your router, then you can try one of the following steps:
- Use our Find Your Router's Internal IP Address guide.
- Download and install our free Router Detector software.
After you find your router's internal IP Address, it is time to try logging in to it.
