CCS: enet_lwip example problem

Tool/software: Code Composer Studio

Hello everyone, I'm trying to run the enet_lwip_m3 example in my Concerto board, but when I get the IP from the serial terminal (putty) i can't upload the website in the  browser (google chrome).

Besides, when I try to ping the IP obtained, I get no response. 

I also have some doubts about the mask and default gateway I've to use.

I use wireshark to see the packets on the network but  I see no packets on the interface.

I believe that the GPIO pin configurations aren't done correctly. I'm using the ControlSuite enet_lwip_m3 example, so I didn't expect to run into any problems.

How can i check if the setting of the connectivity mux connector (ABC) is correctly for the EMAC signals? 

Here they come some pictures to clarify a little bit more what I'm trying to explain:

Thanks in advanced,

regards.
