Getting Secure Home Internet Access While Away
Often you will be away from home but would like to appear as on your home network or access home LAN resources. For this we can use a WireGuard setup which handles the security, even when on untrusted networks. Two routers can handle this for your network setup.
First, a home router that supports Adguard, a WireGuard server, and all running OpenWRT. I bought the GL.iNet Flint 2 router for home: https://www.gl-inet.com/products/gl-mt6000/
Next, a portable router that has a config and cert to your home WireGuard server. This allows your device you want to connect no visibility over the private connections you are about to make. I used the Beryl AX for a portable router: https://www.gl-inet.com/products/gl-mt3000/
Assuming you have a static IP (if not, enable DDNS and use those configs), in the home router create a WireGuard server and generate your WireGuard client config files. Create one for each device, including your portable router, and save on the device that needs them. On Mobile download the WireGuard client and on PC save the configs and upload them to the portable router once connected. Then enable the client and you'll be on your home router! In WireGuard server you can enable things like LAN access to get access to your local Samba Servers, DLNA servers, Linux servers, and more if you wish. Just ensure you keep your access keys secure or you'll have a breach. You can see more step by step instructions here.
Now on public wifi or in a hotel room you can securely access your home network, servers, files, and more. This is great when on untrusted wifi and even works if you need mobile cell phone access to your home network.
Was able to test while out of the country and confirmed no issue and good speed to my home internet. I used this to work remote out of the country with no issue. Since the router contains the WireGuard info, my work PC had no idea that it was on a different network from a WiFi point of view (there are other tracking means, so don't think this is 100% effective). Great way to get around networking and VPN restrictions on your devices as the portable router handles all the connections, with the bonus of any other WiFi devices piggybacking on the portable router also.
