Just found out about http://lpcware.com/content/project/lightweight-ip-lwip-networking-stack targeting NXP LPC parts. You might want to consider this. It has an LPC EMAC based driver (lwip_lpc\nxpcommon\arch\lpc177x_8x\lpc17_emac.c). Yes it is in the 177x_8x folder, but the EMAC block in the 1768 is the same as the 177x and 178x parts, just at a different base address. I think I had to create a login to download the code. So this is a better starting point for LPC micros, but it is impossible that it will just "work". You will surely have to dig into it some. Marty

However, the suggestion you provided are quite complicated to me since I have never worked with microcontroller before. The funny thing is that transplanting lwIP to lpc1768 in my project is not the most important part. So I am trying to find a very quick way to make the TCP/IP stack working while I do not have do dig into the low level C programming(never worked with this before). Is there any suggestion about where should I start or where can I get some source code. PS: Even though I said I need to use Eclipse as IDE, I did try to compile the EMAC example provided by Keil, the driving code (EMAC.c) is aimed for CS8900 EMAC, (but the code in this file only mentioned DP83848c). It did not work in our board. So what is the difference between DP83848c and CS8900 "codewisely"?
