[comp.protocols.appletalk] Many gateways, limited IP addresses.

In the ip.at document in kip0688/doc directory, the last paragraph says:

In the case when several kboxes are on a single ethernet acting as a
backbone between appletalk segments, another simplification is possible.
Rather than having to specify a specific small static/dynamic range for each
kbox (and effectively limiting the number of free slots available on
a given appletalk segment), one can use a special configuration.  All of
the kboxes except one are setup with zero static and dynamic ranges.
Then the final kbox is is setup with a larger range of addresses and a
special configuration flag is set.  This flag allows this box to provide
the assignment and ARP-faking service for ALL the kboxes on the same
ether segment, resulting in more available IP addresses in the pool for
assignment.

This is exactly what I need.  Can anyone tell me what the "special
configuration flag" is?

Actually, I *don't think* this was ever implemented in KIP.  However, K-STAR
allows such a thing.  You run N-1 FastPath's in "AppleTalk only" mode
(or K-STAR mode with the dynamic and static clients set to zero), and the
Nth FastPath in K-STAR mode with a bunch of dynamic and static clients.  Then,
you set option 7 (to allow the FastPath to service clients connected via
the ethernet port).  You then make sure that all N localtalk cables are
in the same zone, and away you go.

Hope this helps.
