This field specifies the number of the TCP or UDP destination port to be
compared with the incoming packet, according to the value configured
for
operator
.

An IP Security table may contain up to 64 entries.
2. Create an
IP Security Access List
to specify whether received or transmitted
(or both) packets are to be checked for each IP Security table defined in the
previous step. It also defines the action to be taken when a received or
transmitted packet matches the criteria defined in the Security table. To
define the IP security access list, you must select
IP Security Access List
from the
IP Menu
. An example of the panel which is displayed is shown in
Figure 184 on page 307.
