Filtering on the LAN Interface
The Netopia R6000 Series offers LAN-side filtering on the Ethernet hub. This permits multiple subnets on the
Ethernet LAN to be kept separate from one another and operate as virtual independent networks sharing a
single Internet connection. Small- to medium-sized offices can benefit by using a single router to connect to the
Internet, with multiple businesses within the office using independent subnets on the network.
For information on creating multiple subnets, see “IP subnets” on page 10-5.
To attach a filter set to the Ethernet hub interface, navigate to the IP Setup screen from the Main Menu.
Any customized filter set you create, can be associated with the Ethernet hub, as well as the WAN interface, as
shown below:
Select LAN (EN Hub) Filter Set and from the pop-up menu, select the filter set you want to associate with the
LAN interface. Press Return.
