- We have some problems with CAP when using Cisco routers to selectively
- route AppleTalk Phase 2.
-
- Our net consists of a backbone net with 10 Cisco routers attached. On the
- other sides of these routers we have local nets for our different
- departments.
-
- We wish to put a CAP file server on the backbone net and let
- all local nets have acess to it. At the same time we want to block all
- access from one local net to another.
-
- We have configured each Cisco in the following way (with obvious
- differences between the Ciscos). This is exactly according to the manual.
-
- access-list 601 permit cable 7-7
- access-list 601 deny other-access
- interface ethernet 1
- appletalk cable-range 7-7
- appletalk zone BackboneZone
- appletalk distribute-list 601 out
- appletalk distribute-list 601 in
-
- where 7-7 is the cable range on the backbone net, BackboneZone is the
- zone on the same net and ethernet1 is the interface on the backbone side
- of the Cisco.
-
- This works well if we put a Mac with file sharing on the backbone net.
- Macs on the local nets can see and access it, but they can't see and
- access the other local nets.
-
- If, however, we put an AUFS server on the backbone net it is *not* visible
- to the local nets.
-
- We have traced the traffic on each net and when the Mac on
- the local net does an NBPLookUp the Mac on the backbone net sends out
- answers addressed to *all* the Cisco routers and they reach the calling
- Mac.
- If we have an AUFS server instead it will only send it's reply to *one*
- Cisco. Consequently the reply will not reach the calling Mac and it cannot
- access the AUFS server.
-
- Whats going on? Any suggestions would be much appreciated.
