Problem with Ethernet port when Router is used in-between

Other Parts Discussed in Thread: AM1705

Hello,

I am using AM1705. I tested the ethernet port by writing a TCP/IP Server socket program in AM1705 device and use TCP/IP Client socket program in a PC in a LAN network.

However, I face issue in communicating with the AM1705 device when the Router's are used in-between (using 2 different LAN's). The setup used is:

a. Router_1 in a LAN network has a PC(running Client program) and Router_2

a. AM1705 device is connected via ethernet interface to the Router_2 (using port number configuration).

From PC (where Client program is running), I can ping Router_2, but not the AM1705 device, as it's in a different subnet. The Port-configuration in Router_2 should re-directs the packets to AM1705 device based on the port number configuration.

I have verified the same setup using 2 PC's. One running Server program and other client program. This shows that my Router_2 configuration is correct. 

Please let me know why Client socket program doesn't connect to AM1705 device. Is there anything missing ?

Regards,

Arul

    Arul,

    Where is the AM1705 getting it's IP address from? Is there any reason it is configured to be on a different subnet? Many routers will use DHCP to give attached devices IP addresses that reside on the same subnetwork so that you do not need to worry about this. If you need the AM1705 to be on a different subnet you will need to configure a static route to it which may be able to be done through configuration of your router, however this is not something that would be supported by TI.
