Access from the Internet
 

The ETH008 can be controlled over the internet almost as easily as on your local network. Your network will most likely be connected to the internet with a broadband router. This will provide NAT (Network Address Translation) and Firewall services. To access the ETH008 from the internet you will need to open up port 17494 (0x4456) to allow incoming TCP connections. Be careful not to open up any other ports. There are a wide variety of routers and we cannot give details for all of them. If in doubt ask your system administrator for assistance. The following shows how to open up a port on a Netgear DG834 router. 

After logging on to your routers setup page, the first thing to do is create a new service. Click on the "Services" menu then "Add Custom Service". Enter a name for the service, select TCP and enter the ETH008's port address for both the start and finish ports. Click "Apply".

 

Now go to the "Firewall Rules" menu and click "Add" in the Inbound services section. Select the ETH008 service and ALLOW always. The "Send to LAN Server" IP address is the ETH008's IP address, 192.168.0.96 in the example above but check what it is on your network. Click "Apply" and that's it. The ETH008 is now accessible over the internet. Before you close the routers setup pages, go to the "Router Status" menu and make a note of its ADSL port IP address. This is the routers internet facing IP address. 

 
 

TCP Test program and example source code To get the ETH008 up and running in the minimum amount of time we have put together an example program and also full source code for this program. You may examine this code or use it as a starting point for your own application.

Android & iPhone Apps We have a free app IO network available for Android and iPhone to remotely control your relays, download from Google Play or iTunes. Search for "Devantech" and you will find the app.
