[comp.protocols.appletalk] Use of a Shiva Netbridge with Gator Mail

msm@energetic.com (Michael S. Maiten) (06/03/90)

I thought that the following question about using a Cayman Gator Box
and a Shiva Netbridge together might be of general interest.

Q> 
Q> At a client's site who has a Shiva Netbridge dividing their LocalTalk
Q> network into two appletalk zones, nodes on the same side (Zone A) as the
Q> Gatorbox can communicate with SUNs (via NCSA Telnet), while nodes on
Q> the other appletalk zone (Zone B) can not.  GatorMail-Q installed on an
Q> Appleshare server (located on Zone B) does not seem to be able to
Q> communicate with the SUN Mailhost (and the mailhost can't get a
Q> response from ping of the MAC server).
Q> 
Q> It would appear that the Shiva Netbridge is not passing the packets
Q> which are needed by the Gatorbox between the Appletalk zones.  
Q> 
Q> Do you have any suggestions as to how we can clear up this problem?

Q> Thank You!

A> Hi Michael,
A> 
A>   There are two problems here...
A> 
A>   First, macintoshes on zone B (opposite side of NetBridge) need to change a
A> line in the config.tel file for telnet.  The line that reads '#zone="Zone"'
A> should be uncommented and the zone A should be put into the right hand side
A> of this equation.  This tells telnet to look in that zone for its gateway to
A> the ethernet.  
A> 
A>   The second problem is more a shortcoming of the MacIP protocol itself.  The
A> protocol does not provide a way for a manually assigned address to be 
A> registered in a zone other than the one that the GatorBox/FastPath is in.
A> This will work for dynamic addresses (as in the above case), but since 
A> GatorMail should run with the same IP address, you should probably move the
A> Mail server to zone A.
A> 
A> Let me know if you have any other questions...
