I have started a QTcpServer for listening like this
server->listen(QHostAddress::Any,53210)
and it has start listening correctly
but, when I connect with Qtcpsocket from another IP (not local)
with this code
socket->connectToHost("IP_REMOTE",53210)
An error has appear (socket Timeout).Another information to help, when I connecti with 3G modem (don't use NAT), connection has been establish well.
Any help?

What is the value of IP_REMOTE??
-
the public IP of the correspondant for exemple 41.xxx.xx.xx
I found that the correspond when he open the port (Port forwarding) 53210, the connection it will establish.
Do you knew how Can I open the port automatically. -
No one have solution?

Hi,
You can't open ports like that. It's in the domain of network setup (i.e. firewall modification etc...)

Are there another solution? Like skype or programs peer to peer, how these programs work?
