How To Configure Access Control List (Acl) For Packets Filtering - ZyXEL Communications GS1910 series User Manual

5.12 How to Configure Access Control List (ACL) for
Packets Filtering
Access Control List (ACL) can be used as a simple packet filtering firewall to filter incoming traffic
and prevent certain traffic from entering your network. ACL groups traffic into data flows according
to specific criteria such as the source address, destination address, source port number, destination
port number or incoming port number, and also define actions to be performed for a classified
traffic flow.
The Switch checks traffic against the ACL rules in the order you list them.
In this example, you configure an ACL rule to identify all traffic coming from host A connected to
port 9 and restrict the host's access to a specific IPv4 network.
Access the Switch through http://192.168.1.1. Log into the Switch by entering the username
1
(default: admin) and password (default: 1234).
Go to Configuration > Security > Network > ACL > Access Control List. Click the Add icon
2
to create a new ACL policy.
Select the port on which the matched traffic is received (All ports in this example).
3
Set Policy Filter to Specific and Policy Bitmask to 0xff to give this policy one ID number in the
4
Policy Value field. You then can apply this policy to a port using this policy ID.
Select IPv4 in the Frame Type field.
5
Select Network in the DIP Filter field and specify the destination address and subnet mask of
6
matched traffic in this policy.
