honeywall picks up all networks from hub

[mat <mr () simla colostate edu>]

my honeywall (honeynet.org roo) is picking up all the traffic from my 
hub, im assuming its because thats how a hub works, but is there any way 
to stop it.  i have two networks set up like this...


internet---hub---honeywall---router---honeynet
                     \---router---home network


i see information on walleye from my home networks IP address.  if it is 
going to log everything from the home network its going to be really 
hard to sift out the data from just the honeynet... can i stop this 
somewhere in the software? thanks in advance
