Failed to map port on openwrt? Maybe a firewall problem?

Possibly. The gateway socket isn't responding, meaning that it couldn't write to the NATPMP port (UDP 5351) on the router at all. Make sure that the NATPMP server is on ( http://wiki.openwrt.org/doc/howto/upnp ) and the port isn't being blocked.

I should probably catch that error in the library so it's not some random socket error being printed to the user's screen.
