The assumption here is that the two subnets are disjoint and connected
by the particular machine in question.

Remember, broadcasts, including subnet broadcasts, are not forwarded
by a level-3 bridge (router).  Since the N1 entries you have installed
mean to use subnet broadcasts for NBP, you will indeed have
difficulties.

The reason all the other machines "worked" is that they probably
communicated to the KIP boxes nearest.  However, you will probably
find that a machine on network 128.6.4 will not be able to "see"
services on a machine (other than the KIP box) on network 128.6.5.

There are two possible solutions - one I do not wish to describe
because it involves undocumented (at the present time) features.  The
easy solution is to use the redirector (atalkrd).  Exactly, how you
will want to set it up depends on aspects of your particular network.
