I wondered if I can get some clever ideas here.
I have this setup currently working for 4G internet in our home:
- A Moto E from Cricket
- Connected by USB to a raspberry pi (tethered)
- Connected to an old cradelpoint MBR900 router (The WAN port in the router connects to the Pi's ethernet port)
- The Pi is running Raspbian and using
Currently, this works great for internet access. We have several devices connected wirelessly to the router and they all get a signal. Browsing works great, even gaming isn't awful.
The problem is with external access. We had a small security system installed, and the provider says they need to program it by connecting remotely in to port 7700. I have port 7700 forwarded from the router to their device internally, but they can't access it.
I'm not able to successfully forward something like 8080 to my laptop either. My external IP address is actually not even ping-able. All requests timeout. 100% packet loss.
So... any suggestions on which rabbit hole I should go down?
