Configuring Access Control Lists - NETGEAR GS748T Software Administration Manual

Configuring Access Control Lists

Access Control Lists (ACLs) ensure that only authorized users have access to specific
resources while blocking off any unwarranted attempts to reach network resources. ACLs are
used to provide traffic flow control, restrict contents of routing updates, decide which types of
traffic are forwarded or blocked, and above all provide security for the network. GS748T
Smart Switch software supports IPv4, IPv6 and MAC ACLs.
The basic steps for configuring an ACL are as follows:
1. Create an IPv4-based, IPv6-based, or MAC-based ACL ID.
2. Use the ACL Wizard or an ACL Rule page to create and define a rule to associate with an
existing ACL. ACL rules define the packet-matching criteria, such as protocols, source, and
destination IP and MAC addresses.
3. Bind the ACL to a port or to a LAG.
The Security ACL folder contains links to the following features:
