lwIP is very widely used and has its own mail list.

Just had a quick look and there seem to be two examples in the files
section
of this group. No idea how good they are though.

Take a look at the Ethernet drivers (emac.c) contained in the FreeRTOS
LPC1768 demos. These are a bit more sophisticated than the ones included in
the LPC2368 demos but I think they are compatible. You would have to change
the interface as they are written for uIP but they will be 95% of what you
want.

There are some good examples of using lwIP with FreeRTOS, but maybe not
on
the LPC2368. For example:

Glad to be able to serve you :o)
