I have just created a simple application, that sends a message to the server, and server replies back. Everything is good in local network, but when I am trying to do the same outsite my network, it is working in following way:
- Client sends packet
- Server receives packet
- Server sends packet
- Client doesn't receives packet.
To send anwser packet I am using InetAddress delivered with DatagramPacket.
What can cause this problem?
