I have a Raspberry Pi computer in the field with a USB modem stick (Huawei E5372). Sim card doesn't accept incoming requests, all ports are disabled by ISP.
I already have access from my desktop using Teamviewer but I want to have my own free ssh access.
I have a no-ip domain because of dynamic IP pointing to RPi.
Is it possible accomplish that in a similar way that Teamviewer does?
EDIT 1: I would need ssh access to RPi from my desktop (Ubuntu) or from my laptop (Win 10)
