I would expect the outgoing traffic to be on the external interface 
(wm0) and the diversion is only on the internal (bnx0)

but I did try to test if something was happening on the internal by 
reducing the address range being matched in the rdr line to something 
that didn't include the internal address of the squid box and it made no
