[lwip-users] PING request not answered

[Alexandre Malo]

Hi,

 

   I am having a problem with the ping request. I have traced in the paquet receiving task and I get the ping paquet. It is well transfered to the ICMP layer.

 

Here is my situation. (Maybe Im just a dummy ip user hehe.. tell me :P )

 

My pc must use the following ip addresses:

     ip = 172.27.37.70

mask = 255.255.224.0

 

My uC (MCF5282) must use the following ip addresses:

     ip = 192.3.1.254

mask = 225.225.224.0

 

I tried it both connected to the network and I also tried an crosswired cable (to remove useless paquet)

 

Any idea why the uC get the ping request but does not reply?

 

Thank you very much!
