APT has announced an update to their AppleTalk routers. They now support
device security across zones. Users can hide a LaserWriter, file server,
or shared modem from anyone not in their zone.
Users in different zones can be allowed different sets of access to different
devices. For example, Zone A may have no access to your LaserWriter but still
have access to a file server, while Zone B has access to all LaserWriters but
not AppleTalk ImageWriters or NetModems.
APT routers connect multiple LocalTalk, Ethernet, WAN, and Serial networks,
and they support AppleTalk Phase 2.
