[Mono-list] Has Anyone Read UDP Data with Mono?

[Alan McGovern]

Hey,

This file creates a bunch of UDP sockets and sends a message to the
routers multicast address:
http://anonsvn.mono-project.com/viewvc/trunk/Mono.Nat/src/Mono.Nat/UpnpSearcher.cs?revision=135259&view=co

This file receives udp messages and passes them off to be processed:
http://anonsvn.mono-project.com/viewvc/trunk/Mono.Nat/src/Mono.Nat/NatUtility.cs?view=co

Hope that helps,
Alan.
