Android testing temporarily on hold.
While setting up port forwarding tonight, I discovered I'm going to have to reset my router settings to default, and rebuild my internal network stuff.
As I have quite a complex-for-a-home-network setup, this alone will take a few hours (or days as I find stuff Ive forgotten).
Sidenote as to why - Netgear 3500L.. port forwarding 'ghosts'. Seems firmware updates leave ghosts in the machine that won't let you re-port forward whats not there anymore, but internally it errors and says it is, because years ago it used to be - yet, trying to connect, gets refused.
Meh, was probably time I reengineer the IP ranges and other equipment anyway. This LAN has grown over the past 5 years.
