Multigate can act as a 'seed' gateway for network numbers and zone names. This information is set at configuration time. If not set, Multigate will use information obtained from another seed gateway. Multigate uses ZIP. > <more stuff - deleted> Use ZIP. >Can someone in Apple explain the rationale of zones, from what I can tell >from the doco and also talking with some of the net people here they are >somewhat of a pain. Zones are useful for what they were originally intended to do - logically group a set of AppleTalk networks. They would be much more useful if some form of (non-kludge) security access existed.
