To test it, fire up Safari, and open http://devnz.com:6699. You should be shown a list of freeview channels, and clicking on one should start live tv. It can take about 12-15 seconds for the video to appear (mainly due to both iPhone buffering and time added by on-the-fly transcoding).
I'll leave the port open for the next couple hours, and hopefully someone will be able to check it.
Thanks.
