This is because atalkad is a static system.  A good rule of thumb is that
you cannot connect any router to an atalkad network unless it is a KFPS
running K-STAR (or KIP), and is entered into the atalkatab for atalkad.

Here is why.  First fact: K-boxes do not send RTMP packets along the routes
they receive via atalkad.  So, you add your new router (Liason) to your
network.  Only networks connected to this network via a TRUE appletalk router
or a sequence of TRUE appletalk routers will discover that this new network
exists and therefore, only routers on those networks can properly route packets
to the new networks (i.e. to your home).  All this basically comes down to
the fact that atalkad is a awful hack and not a true solution to appletalk
routing.  You will learn to hate atalkad later.

A cheap, hacked solution:

Make an entry for the network number you have at home like this:

x.x	K	aa.bb.cc.dd

where x.x is the new network in Kinetics screwy x.x format, and aa.bb.cc.dd
is the IP address of the closest K-STAR (or KIP) KFPS which is already in your
atalkatab.  Then reboot all your boxes (atalkad boot), and have a ball!!
