That application is Digi_ned.  http://digined.pe1mew.nl/   It allows
complete configuration of digipeating and control of the paths and is
able to handle multiple ports.

At one time I had a three band stack running.   Packets chosen to come
out on the other-channels would have information added to the paths
showing where they were originated.  It was possible for users to
manually route return packets to go through the hub to a chosen
frequency and/or destination.

I'll write the whole thing up with the digipeater rules soon..
