    Hi - I'm using udpsend and udpreceive for a network instrument. New problem is that the other player is now on a network were he can't access the router. I guess I can check for open ports, but does any of you know a way to see from the outside which local IP a computer is at - and send to it? /J

      Knowing the local IP of the recipient isn't much use to you - the address is, after all, local. You need to program the router so that it forwards packets coming to its external IP on a particular port to the particular local IP. (It's usually called "Reverse NAT.")

      Yes, we use do bidirectionnal communication. But since we don't have access to the routers on one both sides, I guess its a no go! Thanks for the help anyway.
