The elements (and lists of elements) are referred by rules or rulesets. Elements
are the basic building blocks, and includes IP addresses, host names, networks
(address/prefixes masks), interface names, TCP/UDP port numbers (services),
and other IP header fields (IP Precedence, protocol, etc.).
Lists are named lists comprising of one or more meaningful elements (only some
elements are allowed in lists), as well as references to other lists. A generic packet
type can be used by higher level processing of the packet such as Application
Level Gateways (ALG), and assigned when the packet is initially classified.
BEFORE YOU CONFIGURE CC
Consider the following points before configuring the match-lists:
• If no protocol is specified, then IP is the default protocol.
• Fields that are not referenced in the rule are by default considered a wildcard
match e.g., if the protocol portion of the rule is not specified, it is automatically
considered as an `any' match. The keyword `any' can be used to indicate a
wildcard match.
• Rules start with Line number/Rule number 1 and follow a sequential order. These
rules follow no priority.
• The keyword “from” defines the source port for a TCP or UDP protocol.
• The keyword “service” defines the destination port for a TCP or UDP protocol.
• The keyword “type” defines the header type and kicks in by ALGs (Application
Level Gateways).
