From the commandpromt i can send a message to another IP like: net send 80.222.124.35 Hello world!

But currently I'm behind a NAT router, and I can no longer send messages outside the LAN. Why? And is there a solution to this?

Net send uses broadcasts to the domain.  These are normally not relayed by the router.  Check specifically UDP ports 137 and 138.  Here are a pair of related articles:

"I can no longer send messages outside the LAN"

1. You were able to before then?

2. Where are you trying to send them? Over the Internet, or to a WAN.

3. As mentioned above, one of the jobs of a router is to block broadcasts.

first of all sorry for the long response time

second, my guess is that is completly impossible to send a such thing over Internet? Working fine over LAN though, so my guess is that it don't work. Had a friend trying via his connection and he could'nt either.


Now, what to do with this question? Close or give points?

It's up to you.

You can over the Internet using very specific circumstances and provided that all the connections between you and the other person do not block that type of traffic in which they most likely do.

You would also need to  use the Internet IP address of the other person's computer unless your could resolve their address using an Internet DNS adddress

yes, that should do it if all conditions are met.

The port needs to be open over the whole connection and the messenger service needs to be running on each computer.
