Have you enabled any debug messages in your build ? What do they say ? 
You can turn on debug in the Common Ethernet Support package 
(CYGDBG_IO_ETH_DRIVERS_DEBUG). You may also be able to enable extra 
debug in the Ethernet driver itself.

Have you checked with Ethereal/tcpdump whether any traffic is actually 
leaving your board ? Do you have any LEDs on the Ethernet port, and do 
they light up when you start your application ?

Can you see any messages like "client IP: 10.0.0.1" when you start your 
application ? Depending on your configuration it may be necessary to 
call init_all_network_interfaces() in your applicaiton. However, if 
loopback is working then maybe this isn't necessary.

Without more information like this it is difficult to guess what your 
problem might be.

Kelvin.
