We have a LocalTalk network and an Ethernet set up as follows:

           LW+           Mac    LW II     Mac .. Mac
            |             |       |        |      |
            |             |       |        |      |
     ---------------------------------------- .. ----------- LocalTalk cable
                   |                                      |
                   |                                      |
             ------------                             --------------
             | GatorBox |                             | Mac Server |----LW II
             ------------                             --------------
                   |                                      |
                   |                                      |
     ------------------------------------------------------- Ethernet cable
             |                      |                |
             |                      |                |
            UNIX                   UNIX             Mac
    LW+----(CAP)                FileServer


The GatorBox is set up to do KIP encapsulation, and to convert NFS to
Apple's network filesystem.

The Mac Server is running the AppleTalk Internet router to route between all
three attached networks (LocalTalk cable, Ethernet, and local printer).

We have the following problems:

- Macs on the LocalTalk cable can see all printers and fileservers,
  including the printer attached to the UNIX machine and provided to AppleTalk
  via CAP.

- The Unix machines can see all printers and fileservers on the LocalTalk
  cable and provided via CAP, but cannot see resources on the Ethernet cable.

- The Macs on the Ethernet can see resources on the Ethernet cable, and on
  the LocalTalk cable, but cannot see resources provided via CAP or the
  GatorBox.

It appears to me that the following logical network has been set up:

    KIP on Ethernet  ------------  LocalTalk  ----------------  EtherTalk
  -------------------| GatorBox |-------------| Apple Router |-------------
                     ------------             ----------------

and that the GatorBox and Apple Router are not exchanging routing
information, so that machines on KIP can't see EtherTalk and machine's on
EtherTalk can't see KIP.

The GatorBox is supposed to route between EtherTalk and LocalTalk/KIP
(according to the documentation), so the Apple Router should only be
required to access the LaserWriter attached to the server. It doesn't seem
to be doing so.

My questions are:

1) What am I doing wrong?

2) How do I set things up so that all machines can access all resources?

	Thanks in advance...
