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?
