Simple Python UDP Server: trouble receiving packets from clients other than localhost
<p>So, the very simple code that I'm trying to use is here: <a href="http://wiki.python.org/moin/UdpCommunication" rel="nofollow">http://wiki.python.org/moin/UdpCommunication</a></p>

<p>(also here):
Sending:</p>

<pre><code>import socket
UDP_IP = "127.0.0.1"
UDP_PORT = 5005
MESSAGE = "Hello, World!"

print "UDP target IP:", UDP_IP
print "UDP target port:", UDP_PORT
print "message:", MESSAGE

sock = socket.socket(socket.AF_INET, # Internet
                 socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))
</code></pre>

<p>Receiving:</p>

<pre><code>import socket

UDP_IP = "127.0.0.1"
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, # Internet
                 socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    print "received message:", data
</code></pre>

<p>The code works fine when I run both applications on my computer.  I put the sending code on my laptop with:</p>

<pre><code>UDP_IP="IP address for my computer"
</code></pre>

<p>Everything else is the same.  Yet, nothing happens.  What am I doing incorrectly?  I used wireshark and determined that the packet is being sent and received; however, the python program isn't receiving the packet.  I'm very confused.</p>

<p>Any help is much appreciated.
Thanks in advance.</p>
