We have a very large, diverse (technologically, geographically and politically) campus Ethernet (broadband) network, and are having to run multiple AppleTalk network numbers on it so that various departments don't have to see each other's machines and printers (and, more importantly to them that they can't access each other's equipment). Only problem is when you throw a Mac in with an Ethernet board with EtherTalk enabled. The Mac associates itself with (potentially) a different network each time you fire up the chooser (it picks the network number associated with the last AppleTalk packet that it saw on it's Ethernet interface). Question: does anyone (hello, Apple, 3Com and Kinetics) know of a way to hardwire an AppleTalk network number into a Mac so that it is always associated with a certain network? Thanks! L.

No, no, no! This is NOT the way of doing it! Never run more than one EtherTalk on one ethernet! If you have to, get bridges that can filter specified protocols, and turn of EtherTalk (2 types!). Then get some kind of EtherTalk router (A MacII with several ethernet interfaces and some software) to connect the logical ethertalk networks. The mac does not get it's network from any passing packets, but from RTMP-packets, and normally it asks for it. >Thanks! >L.
