WCF and NAT traversing

Hi,

I'm trying to write a simple IM which will be based on WCF. For NAT
traversing I use STUN method to get public addresses of peers. That
implies the use of UDP transmission, but it is not implemented in WCF.
I found the UDP Transport Sample and I managed to set up the service,
but i have problems to configure the client. Client receives the
address of service and has to configure the connection from the code,
without use of App.config file.

I'll be thankful for any help

At this point, I don't know of any .Net implemetnations of STUN / TURN /
ICE. I've been looking for a while, and never quite got up the energy to
write them.

I don't know what type of luck you'll have trying.

The Vista IPv6 stack has quite a bit of NAT traversal stuff in it, as does
the MSN client, but I'm not sure if WCF can leverage either of those. I
would be interested in seeing what you find out.
