SmartSwitch Router User Reference Manual 217
Chapter 13: IP Policy-Based Forwarding Configuration Guide
The following is the IP policy configuration for the Policy Router in Figure 20:
Authenticating Users through a Firewall
You can define an IP policy that authenticates packets from certain users via a firewall
before accessing the network. If for some reason the firewall is not responding, the packets
to be authenticated are dropped. Figure 21 illustrates this kind of configuration.
Figure 21. Using an IP policy to authenticate users through a firewall
Packets from users defined in the “contractors” group are sent through a firewall. If the
firewall cannot be reached packets from the contractors group are dropped. Packets from
users defined in the “full-timers” group do not have to go through the firewall.
