Figure 5-25 Example of the host validator configuration (1)
Example: If you find a suspicious host (with the IP address 10.1.1.2) in an external
network, you can set the host validator policy as below to block its attack on the internal
host.
Figure 5-26 Example of the host validator configuration (2)
As shown in Figure 5-26, inbound is selected from the [Direction] drop-down list, and
thus the device only block the data from the address 10.1.1.2 to the internal host while
the internal host can still send data to the address 10.1.1.2.
Caution:
z The host validator can be used to limit the data stream between the WAN and LAN
ports.
z The security policy takes effect only when the firewall is enabled.
