Is there a port of LwIP for LPC23xx, possibly using freeRTOS? I can't
seem
to find any port for LPC23xx series.

Just like FreeRTOS, most of the lwIP code is common to all platforms,
and the port layer is very thin.
lwIP ports need two port layers - one to the kernel being used (unless
you just using it in a superloop), and one to the hardware.
The kernel port layer that stitches lwIP and FreeRTOS together are in
common use. See:
http://www.freertos.org/FreeRTOS-Plus/FreeRTOS_Plus_IO/Demo_Applications/LPCXpresso_LPC1769/NXP_LPC1769_Demo_Description.shtml
for an example running on an LPC1769.
The hardware port layer is just a MAC driver, so naturally changes
depending on the microcontroller/MAC hardware being used. It is more an
exercise in providing a MAC driver, rather than am exercise in porting
lwIP, so you can take an existing FreeRTOS/lwIP example and replace the
MAC driver for whatever chip you are using, and you have what you want.

Thanks Richard,
I will look into the example you have provided and replace the MAC driver.
