I also had a look at Alex Tweedly's UDP examples when I started looking at networking with Rev. - saved a lot of time. I've also got two very minimal test stacks on user space Jock_McTartan - about 10 lines of code each - client and server.
They have just enough in them to show the mechanism working.

Hope this helps.

Folks,

I have two stacks, one is a udp server stack and the other is a client stack. The server is setup to use the newPacket callback message when a datagram arrives. The client will write to the server then it will read from the socket to see if there was any answer.

The client is able to write to the server fine, the datagrams arrive nicelly. The server is not able to answer back, no error is reported by the write to socket message but nothing is returned to the server, the read from socket message after the write to socket on the client returns empty. I've sent more than 1k packets, they could not be all droped since on one way it all works fine but on the other way they simply don't work.

Am I doing something really stupid?

My packet size is 576 chars, I've also used 8k and 2k sizes, the client is able to send those fine and they arrive intact, but from server to the client I can't seem able to communicate.

thanks in advance, udp is kinda new to me.
