[comp.protocols.appletalk] FastPath - NetBridge Incompatibility

powsner@nlm-mcs.arpa (Seth M Powsner) (02/03/90)

Sorry if this repeats my prior attempt to post (appeared unsuccessful)--
The Kinetics FastPath 4 running K-Star V7 uses name binding protocol requests
to confirm a node's continuing use of a dynamically assigned IP address. This
is blocked by Shiva NetBridge's privacy option which attempts to hide a
private AppleTalk subnet request. It never passes name requests so the public
side never "sees" anything. The TCP-IP session can be started, but after 2.5
minutes the FastPath assumes it stopped (no name requests returned). Static
address sessions don't even get this far because a name request is used to
"firm-up" the TCP-IP session initialization. Kinetics and Shiva are aware of
this. No fixes. Cayman tech support says the GatorBox would act similarly.

Can anyone suggest alternative hardware/software? We'd like to keep our
office AppleTalk net out of sight (over and above password protection on
our TOPS file servers). Alternatively, anyone know of monitoring/alarm
software to let us know that someone's attempting to crack the password
on the file server?
