Chapter 11 Firewall The following table describes the labels in this screen. Table 45 Security > Firewall > Rules LABEL DESCRIPTION Rules Storage Space Usage Add New ACL Rule # Name Src IP Dest IP Service Action Modify This read-only bar shows how much of the Zyxel Device's memory for recording firewall rules it is currently using. 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 transport the packets for which you want to apply the rule. Displays whether the firewall silently discards packets (Drop), discards packets and sends a TCP reset packet or an ICMP destination-unreachable message to the sender (Reject), or allow the passage of (Accept) packets that match this rule.
