I want to just dump all the packets between two satelite links without checking for ack back and forth which creates latency and long ping times.
For that I want both the peers between satelite links to take care of that and be able to deal with routing the traffic flow out again.
I am not sure what solution would be appropriate for that problem and I am very open for suggestions.
What I want is a solution which does not requires 3.rd party software/hardware (I am aware of the existing ones). I want it to be able to run on FreeBSD.
