Re: Hitron troubles OK, problem may be solved. I had enough of the Hitron's crap, so I put it in bridged mode so I could setup my old router. But my old router appears to be dead, so I had to reset the Hitron...
Just for shits and giggles I tested UPnP right after resetting it, and it worked fine! So I figured I would slowly configure it, and after each change test UPnP to see at what point it would stop working.
Didn't take long, my very first change was to switch to 10.20.30.1 instead of 192.168.0.1, and it broke after that. Tried several other IPs in different ranges, and they all failed. Reverting to 192.168.0.1 got UPnP working again right away.
I also added a port forward and rebooted the router, and unlike before it persisted.
So apparently it's a good idea to stick to 192.168.0.1 if you don't want mysterious shit to happen to your Hitron!
