Hi, I have an Arduino & a WiShield setup connected to my home network which uses an Airlink 101 router connected to Comcast. The Wishield is used to send out emails via a PHP page. What I want to do is ping the WiShield from my blog using a PHP page. I have the PHP page setup where I just type in a url and it pings it. Once it is working correctly I will automate it. My 2 questions are: 1. How do I know the address of my home network and WiShield ? 2. If I am using a PHP page, do I want the HTTP option for port 80 when setting up port forwarding?
