Scenario 7-4: IPX Filtering 507
Given the network in Figure 7-14 and the configurations in Example 7-17 through 7-20, answer
the questions and perform the tasks that follow.
1
Characterize the traffic that is discarded due to the access lists used on Atlanta. Can clients
in the remote sites access the servers in Atlanta?
2
Create IPX packet filters to meet the following criteria:
-- Clients in Nashville and Boston are not allowed access to Server 1.
-- Clients in Charlotte are not allowed access to Server 2.
-- Use standard access lists, if possible.
-- Place the access lists close to the source of the packets.
-- Assume that all access lists from Task 1 have been disabled and deleted.
3
Create SAP filters that perform the same function as described in Task 2.
