Add IP Based Rule Page
The
Add IP Based Rule Page contains the following fields:
• ACL Name — Displays the user-defined IP based ACLs.
• New Rule Priority — Indicates the rule priority, which determines which rule is
matched to a packet on a first-match basis.
• Protocol — Creates an ACE based on a specific protocol. For a list of available
protocols, see the Protocol field description in the
IP Based ACL Page above.
• Source Port — Defines the TCP/UDP source port to which the ACE is matched.
This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select
from List drop-down menu. The possible field range is 0 - 65535.
• Destination Port — Defines the TCP/UDP destination port. This field is active
only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-
down menu. The possible field range is 0 - 65535.
• TCP Flags — Filters packets by TCP flag. Filtered packets are either forwarded
or dropped. Filtering packets by TCP flags increases packet control, which
increases network security. The possible field values are:
• ICMP — Indicates if ICMP packets are permitted on the network. The possible
field values are as follows:.
• ICMP Code — Indicates and ICMP message code for filtering ICMP packets.
ICMP packets that are filtered by ICMP message type can also be filtered by
the ICMP message code.
