How can I remote access GSM based device?
Due to the powers that be I'm stuck with a head scratch.
I want to be able to SSH into my remote Linux machine, normally not a problem. My problem is that the IP address I need to SSH into is dynamic, again, not a problem once I know the IP address.
The problem is that the IP address is on Vodafone's mobile broadband network and therefore incoming traffic to the GSM modem is being blocked by Vodafone.
How can I get round this, bearing in mind that I just need access to Busybox on the remote device. I have looked at openVPN but don't quite understand if that would be of any use? Could there be another solution?
