Cisco RV 110W Firewall Features

You can secure your network by creating and applying rules that the Cisco RV

120W uses to selectively block and allow inbound and outbound Internet traffic.

You then specify how and to what devices the rules apply. To do so, you must

define the following:

• Services or traffic types (examples: web browsing, VoIP, other standard

services and also custom services that you define) that the router should

allow or block.

• Direction for the traffic by specifying the source and destination of traffic;

this is done by specifying the “From Zone” (LAN/WAN/DMZ) and “To Zone”

(LAN/WAN/DMZ).
