I know, I did that - in fact I set up two transit points but the problem is that for some reason the ORIGINAL UDP IP is sent along with the packet, not the IP address of the node doing the resending of the packet.

It’s not your fault, I hope you didn’t read it as that - it’s definitely the correct behaviour on part of the bridge and probably actually probably the correct behaviour for socat..


Basically, in summary, this was the setup


NODE A:4711	-> 	TRANSIT:4711 	-> 	NODE B:4711
NODE B:4711	->	TRANSIT:4712	->	NODE A:4711

Node A is expecting packets from TRANSIT:4712, but sees packets from NODE B:4711
Node B in turn expects them from TRANSIT:4711, but sees packets from NODE A:4711.

So end result = dump the weird looking packets.
