Is this a correct assesment? It is true that with K-STAR (and KIP), one uses up IP address space from the ethernet side of the FastPath in order to provide IP addresses for Macs on the LocalTalk side. This is somewhat of a problem in certain cases (such as yours). The thing that makes it hard to do what you want in the FastPath 4 (and this problem essentially correlates to engineering hours) is that K-STAR does not provide all the functions of an IP router. In particular, K-STAR does not have any means of sharing with other hosts and routers that it is a path to IP subnet "X". (If K-STAR were to do this, it would probably use RIP, the protocol which Berkeley 4.x machines speak [as well as a substantial number of other entities including most "real" IP routers].) Since we don't tell anyone how to get to IP subnet "X", an installation need to set up default routes (or at least one) to IP subnet "X". This capability IS on a list of things to do to the K-STAR code, but there is no specific date or time associated with it. Your best bet is to inform your sales rep at Kinetics (or the dealer you purchase through) about your needs. Greg Minshall ...ucbvax!unisoft!kinetics!minshall (415)947-0998
