ACLs are lists of conditions that are applied to traffic
traveling across a router's interface. These lists tell
the router what types of packets to accept or deny.
Acceptance and denial can be based on specified conditions.
ACLs can be created for all routed network protocols, such
as Internet Protocol (IP) and Internetwork Packet Exchange
(IPX).
ACLs can be configured at the router to control access to a
network or subnet.
Some ACL decision points are source and destination
addresses, protocols, and upper-layer port numbers.
ACLs must be defined on a per-protocol, per direction, or
per port basis.
The following are some of the primary reasons to create ACLs:
Limit network traffic and increase network performance.
Provide traffic flow control.
Provide a basic level of security for network access.
Decide which types of traffic are forwarded or blocked at
the router interfaces. For example: Permit e-mail traffic to
be routed, but block all telnet traffic.
Allow an administrator to control what areas a client can
access on a network.
If ACLs are not configured on the router, all packets
passing through the router will be allowed onto all parts of
the network.
i think it's enough to understand..
