1. Thx for quick and nice reply laugh
2. Does this mean if i know which ports the clients routers are using client1 can also send a package directly to client 2 using the port 38495?
3. So this means if I don`t manually do portforwarding and tell the router which port it has to use it just gonna choose a random port that is usable if i send package from a pc behind a router, to the server.
4. Now I think the header of every package contains the port it was sent from but how can the server find out the port? Is there a function to find it out?
5. Thx for your great help
