client<->server<->client

[Islam Alshawish]

Hello;
i need to use echoUdpClient/Server applications to
- create 3 nodes, one server and two clients
-send a message from first client to the server and relay on it to forward
it to the other client.

Is that possible using the mentioned apps?
how to modify server to pass message to the second client (and also from
the second to the first)

BR,
Islam

Normally the middle node would be a router. After all, that is what a router does, forward packets. The left node could run UdpClient, the right node PacketSink, and the middle node doesn’t even need an application.

I need to do farther process on this packet content, I need to implement a
security mechanism I am working on, that why I need to install an app like
a server which processing message form the first client and send it to the
other one. By the way I need a way to do this as well as to be scalable!
How can I do this?

You’ll have to write your own application for that. It will act like UdpEchoServer in that it will listen for incoming traffic, and act like UdpEchoClient in sending out packets, after transforming according to your scheme.

Actually I am trying to do that, but I am wondering how I can specify in
the Server app the address of the second client? It handles the address of
the sender client and echo to it! What I have to do to add next client/s
addresses as well as is it correct to install the udpechoClient app in the
second one?
I hope my point is clear!
Thanks
