Richard, thank you very much - this post is exactly what I need. Python supports recvmsg, and sendmsg from version 3.3, but Twisted has its own implementation that is 2.7 compatible. I'll try that right away. I think it's best to include the recvmsg/sendmsg code into my DatagramProtocol subclass. Best Regards Maciek 2013/10/16 Richard Wall <m-lists@the-moon.net>

All in all the problem with using wrong source address can be easilly solved with a bit of user attention, however it's hard to find the solution that "just works".
There's an OS API (recvmsg?) that lets you get at this information; I believe Twisted has the start of a wrapper for it. Given a full wrapper we could create a new UDP API that did support this easily.
Here's a good description of how PowerDNS solved this problem using recvmsg: * http://bert-hubert.blogspot.nl/2012/10/on-binding-datagram-udp-sockets-to-an...
I don't think it's currently possible to listenUDP on a specific IPv6 address: * https://twistedmatrix.com/trac/ticket/5086
But the branch for that ticket is almost ready to be merged... it just needs a few custom exception classes I think.
