[lwip-users] address@hidden

[Robert Schilling]

Hi guys,
I'm using a board based on the LPC1768 with Ethernet in combination with KEIL as IDE.For this reason I used the LPC1766 example with lwIP Stack
 (http://www.coocox.com/EXAMPLE/NXP_LPC1766_ARMCC.htm) .

I compiled this for my host processor, everything fine :)
But when I debug it, I don't get a real connection. ARP Requests are coming in but the server doesn't reply.   
Here is my debug output:
