Kristoffer Nilsson added the comment:
Ah, bad formulation by me. While testing I had both the same machine and
external machine sending UDP packages to the port I was listening to.
The listening server would not receive anything on 64/64bit (unless running
from IDLE).
The reverse try
New submission from Kristoffer Nilsson :
Running Windows 7 Enterprise 64 bit, and Python 7.2.1 64 bit Python failed to
read and send UDP packages when ran in cmd.exe. This is not the case when ran
with IDLE.
Example; two simple programs. First one listening to a UDP port
sock = socket.socket
