Figure 5.4: IP Security Menu
The IP Security Menu lists five IP Security "masks" along with the selected permit/deny
action for each mask.
Each Security Mask prompt is used to define a specific IP address or range of IP
addresses. Each Mask Action prompt is used to select the permit/deny action for the
corresponding mask.
.
Masks are listed in order of ascending priority; Mask 1 has the lowest priority, and
Mask 5 has the highest priority.
b.
Masks have a cumulative effect; high priority masks supersede the effect of lower
priority masks.
c.
Each IP Address consists of a series of four eight bit numbers. The number 255 is
used as a wild card.
d.
3.
Example 1: Deny access to all hosts except 192.1.1.5:
Security Mask #1: 255.255.255.255
●
Mask #1 Action: Deny●
Security Mask #2: 192.1.1.5●
Mask #2 Action: Permit●
Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants
access to 192.1.1.5 only.
Example 2: Allow access only by addresses that begin with 192:
Security Mask #1: 255.255.255.255
