I am trying to solve one project for me. I have sms gateway running on raspbian wheezy (it is something for monitoring). I know how to connect the sim card (data one) into the internet but it gets some ip from the provider/vodafone DHCP server (10.184.84.xxx, with netmask 255.255.255.255) what i obviously could not connect at.. it is on interface ppp0.
So i was wondering if there is a way to dial a VPN through the sim card into my server to get access to the web gui and manage the device in the case that the network goes down.
Thank you very much for any advice.!
