Well, for one thing, AppleTalk protocols over Ethernet are not IP, so
IP firewalls will have no effect. If, however, you are encapsulating
AppleTalk in IP, you will have to get a firewall or tunneling software
that is smart enough to filter on specific AppleTalk services.
You cannot, of course, filter on specific AppleTalk node addresses. Rather,
you will have to filter out Networks, Zones or Name Binding Protocol names.
For services, you will have to filter based on Datagram Delivery Protocol
socket IDs. I'm not sure if there is a published list of these, but
you may want to check out some of the Mac FTP archives like info-mac.
I am not aware of any products that do any of this currently, but it's
not an easy prospect.
Good luck!
