I have an Arduino Mega 2560 and Ethernet shield. The Mega and Shield have a matching connector for ICSP. I am unable to get the example client or server programs to transmit/receive anything. The serial monitor indicates the programs are running. I am sure this is not a network issue.
Reading the forum suggests that in need to map pins 10-13 to 50-53 but I am not sure if the linking ICSP connector overrides this requirement.
Also, if I need to link pins 10-13 on the ethernet board to pins 50-53 on the Mega, do I need to bend out pins 10-13 on the ethernet board so they don't connect to the mega?
I finally found the issue... The ICSP from the ethernet shield was not reaching far enough down onto the pins of the Mega 2560 ICSP. I found that I had to tilt the ethernet shield down at the ICSP end. Now the client and server example code work.
