Question

I am trying to filter and edit incoming and outgoing UDP network packets.

So if the machine were to send "data-hi" I would like to be able to filter that so it does not get sent, and instead send out "data-changed". Same goes for incoming, if a machine were to send me "data-hello" I would like that to be interpreted as "data-welcome".

Kinda like a firewall type thing, capture edit.
