I have a friend that lives in farm country in Michigan, His DSL services has given him like 12 mbps services down and 1 mbps up and now T-Mobile has advertised that he can get 5G services from them that supposed to have better speeds and probably better reliability than what he is getting from the local ISP.
The issue is that right now he has ports opened for VPN access to his network and T-Mobile’s 5G networking option is CGNAT. I have done a lot of searching on how to do a VPS/VPN relay option but there doesn’t seem to be a really good article on this. My thoughts are to have his router behind the 5G gateway VPN into a VPS and have the VPS relay inbound connections to his network.
If there is any articles on this that you have used in the past as a guide can you please provide the links?
