I'm using the socat command as follows:
socat -T10 UDP4-LISTEN:port,reuseaddr,fork TCP:host:port
on the client side and the command
socat TCP4-LISTEN:port,reuseaddr,fork UDP:host:port
on the remote end to send udp packets bidirectionally between the source and the destination. Is it possible to compress the data being sent to and fro?
I've been looking into this issue myself. I'm trying to set up 2 points, one in CentOS and another on Windows Server that use compression. I've looked into socat and the only option seems to be using SSL compression over that connection. I'm also investigating PPP but it seems to have fallen out of use.

Good luck there mate.
