IPX Packet Forwarding Filter Example
Figure 4 IPX Packet Forwarding Filter Example
Router A
HR File Server 1
Internal Net = 10
In this example, an FDDI backbone connects several departments in an
organization. Routers A, B, and C connect the departmental networks to the
backbone. Within the organization, users can access all servers. However, the
Human Resources (HR) servers can be accessed only by HR employees. To
make the HR servers secure, packet forwarding filters are used in addition to
the usual NetWare password security. Note that some of the HR employees
are connected to different networks than the one HR servers are connected to
Figure 4 shows the internetwork topology.
HR Employee 1
IPX Node = 59:00001B2700F3
Corporate FDDI Backbone
IPX Network 50
HR File Server 2
Internal Net = 12
Routers B and C do not require filters because users can access all corporate
servers (except for the HR server). Packet forwarding filters are installed on
Router A to block packets from the FDDI interface to the HR servers, except
when the packets are from the nodes 59:00001B2700F3 and
55:00001B2700F0.
When configuring this example, set the parameters as shown in
