I am using LPC1768 Development board. I have successfully used Easyweb example given in keil with my board. its working when i am connecting my board directly to one of my pc. Everything is working fine but when i connect my board with LAN and access my board with one of my PC in LAN.... that time its not working properly.... means i am getting ARP request.... it is getting processed and also sent reply but PC that has sent the ARP request is not getting this reply. My board and PC is connected through dlink switch. I am afraid Switch is dropping my packets.
Any suggestions??!!!
Have you correctly configured it - and any/all other network equipment involved - to allow this communication?
Sir,
Thanx for ur reply.
Yes sir I have correctly configured it with one of the free static ip and gateway ip address and both Connection are under same subnet mask.
EasyWeb works perfect when I connect it directly to PC with Straight cable. But When I connect it to My LAN using one of LAN connection and when I access my board from one of my pc of LAN... It gets ARP request from client PC successfully.... and my board processes that request and prepares reply (I am using debugger) but client PC is not receiving this reply.
My board is configured for RMII. There is only one equipment in between my board and PC that is Dlink switch.
I am using Wireshark on my PC to get network traffic info.
??????????
Help!
I think there is no problem with software. May be problem is with Phy settings or Phy hardware.

it it written in datasheet that pin 20 and pin 21 of DP83848 must be connected to 3.3 V through 2.2 K ohm resistor but in my board that pin has been left float.
can it be a problem?
