DESCRIPTION
This read-only bar shows how much of the Zyxel Device's memory is in use for recording
firewall rules. When you are using 80% or less of the storage space, the bar is green. When
the amount of space used is over 80%, the bar is red.
Select an index number and click Add New ACL Rule to add a new firewall rule after the
selected index number. For example, if you select "6", your new rule becomes number 7
and the previous rule 7 (if there is one) becomes rule 8.
This field displays the rule index number. The ordering of your rules is important as rules are
applied in turn.
This field displays the rule name.
This field displays the source IP addresses to which this rule applies.
This field displays the destination IP addresses to which this rule applies.
This field displays the protocol (All, TCP, UDP, TCP/UDP, ICMP, ICMPv6, or any) used to

a TCP reset packet or an ICMP destination-unreachable message to the sender (Reject),
