I have a big problem, I live in an area where there is no fiber or ADSL connection and I connect to the internet using a 4g+ sim in a 4g+ router (Tp-Link Archer MR600). The connection is just fine: ping ~50ms - dw 240mb - up 50mb but there are a couple of issues that are driving me crazy.
- My ISP does not assign me a public static IP, I have a private IP maybe they are using a double NAT or CGN, I don't know.
- My connection goes down and up, every 4 hours, they do some sort of IP update for I don't know what reason.
I can't open doors, host anything, access video surveillance cameras remotely and a lot of other things. I am paying a lot of money for the contract, and this is the only ISP with decent bandwidth and stability, but what I have listed above prevents me from doing a lot of operations. For example if I am connected to a VPN every 4 hours the connections are interrupted, and I have to reestablish it manually.
Maybe (surely) there is someone here who has a better knowledge and I will be happy if someone wants to give me some clarification or even better some tricks to make things work.
Ask me if you need some kind of output I will post it.
As another note feel free to give any suggestion, I don't know what can be useful. Some kind of connection mesh, VPN or any other solution should work I will give it a try.
Maybe could be a wrong configuration or something similar but I don't think so, the ISP is locking me in some way.
Things that I tried:
- IP address reservation
- Connecting 2 routers in cascade
- MAC address cloning
- Static routing
