Hey Guys,

So my work has a requirement for some systems to send data over GPRS etc . To make it fully functional, it needs to be publicly routable.

So the system makes an outbound connection to another system, says "this is my IP address" - and then the other system need to initiate TCP sessions back to that IP address.

Outbound connection is fine - but coming back in not so much. 

Does anyone know what the APN settings etc I need are for getting a routable/non-NAT'd IP address?

Yes, I realise there is a sticky thread at the top of the forum - but it's 10 years old!
