5.3.4.1. IP Security Feature
The IP Security feature can be used to restrict unauthorized IP addresses
from establishing a connection with the IPS. In the default state, the IPS
accepts incoming IP connections from all hosts. To configure the IP
Security feature, proceed as follows:
1. Access the IP Security Menu:
a) Web Browser Interface: The IP Security feature is configured
using the fields at the bottom of the Network Parameters Menu as
shown in Figure 5.9.
b) Text Interface: Go to the Network Parameters menu ( /N), type
5 and press [Enter]. The IP Security menu will be displayed as
shown in Figure 5.11.
2. The IP Security menu lists five IP Security "masks" along with the
selected permit/deny action for each mask.
a) Each Security Mask prompt defines a specific IP address or range
of addresses. Each Mask Action prompt defines the permit/deny
action for the corresponding mask.
b) Masks are listed in order of ascending priority; Mask 1 has the
lowest priority, Mask 5 has the highest priority.
c) Masks have a cumulative effect; high priority masks supersede
the effect of lower priority masks.
d) Each IP Address consists of a series of four eight bit numbers.
The number 255 is used as a wild card.
