Ethernet Shield works over network but not over internet

Hi,
I’m having problems connecting to to internet with my Arduino. I have an Arduino Mega 2560 coupled with a Seeed Studio Ethernet Shield. I am able to control an output on the Arduino from a computer connected to the same network as the shield, but not over the internet. I’ve tried both at home and at work with the same results, so I don’t really know what to try next. Does anyone have any suggestions?

Thanks,
hamwich

Hi hamwich ,
You can use it connected to internet as slave such as Twitterslave or PachubeClient , but if you want it work as server via external network , you should be need a apply for a website , and other demo code is necessary. You can ask for this on the arduino official website , that will be a answer .
