Ardumote

I am trying to use Ardumote, but I am having no luck. I have followed the website instructions and spent all day researching on the net. I have a R6200 netgear router and I think that is were I am having the issues. I have tried to open and configure port 7777 to be able to port forward, but I can not get my iPhone to control the Uno and Ethernet shield. Anyone use this setup and have these problems?

A link would be useful.

but I can not get my iPhone to control the Uno and Ethernet shield.

I can get my iPhone to send GET requests to, and receive replies from, my Arduino with Ethernet shield, using the browser. Why can't you?
