4.8.1. Access Control Lists
Access Control Lists (ACLs) allow the LibraPlus to permit or deny packets from specific IP addresses
to specific destination IP addresses and ports. They also allow the LibraPlus to specify different types
of traffic such as ICMP, TCP or UDP.
The typical ACL entry consists of four essential parts:
• identifier of the ACL is a positive integer number that identifies the list. New entries are added to
the end of the list.
• action is a keyword describing an action applied to the matched packet. Two self-explanatory
keywords are possible: permit and deny .
• source specifier is a host or a network address followed by an optional TCP or UDP port.
• destination specifier goes after the source having the same format, which is described more in more
detail below.
Entries may also include optional fields:
