Hello,

I am using a modem and a router in my home network and I can play games without port forwarding. (Although I have uPnP; does that let games go through the router firewall?)

About pinging src and dst machines; do you simply mean pinging the client IP from my computer? If so yes, I have no problems with it.

If I send a packet to an outside client with IP/port, if he binds/listens on his local IP/port the data will be forwarded to him right? Because the Socket.bind specifically says binding a socket to the local IP/port.

Gonna have to try that, but the problem is right now when a new client arrives, he is given his own UDP socket. When he sends data to that socket, it is sent through every other UDP socket except that one. Since you can only have one socket listening to a IP/port, how would this go about if the server listens on 53 for all its sockets?

Does all kind of data go through common sockets like that? Again, the example of video games. Are they all using that very port or how do they manage to send/receive?

Does a firewall stop incomming UDP traffic like that? For example, if I fire up a game like Call of Duty, I havn't configured port forwarding for any steam/call of duty ports and yet my packets get sent/received.

Also, I keep mixing it up; If I send packets to a global address, does that global address also contain the local IP of the target machine or does the router resend the packet to any local client listening on that specfic port?

Wrong language though, that's C++ :p
