Not sure if I already explained this: communicating from Linux to Linux via UDP over a RTnet network takes RTmac/TDMA set up on both nodes. Once you have RTnet on one node, the Linux stack is isolated. The rtnetproxy opens this slightly by allowing TCP to be forwarded directly over RTnet (instead of being encapsulated in RTmac frames). If you are *really* sure that you also need UDP like this (I expressed my concerns earlier), you are welcome the enhance the rtnetproxy to provide this forwarding for any IP packet that the real-time stack doesn't care about.
