Cisco RV220W Firewall Features
You can secure your network by creating and applying access rules that the
Cisco RV220W uses to selectively block and allow inbound and outbound Internet
traffic. You then specify how and to what devices the rules apply. You can
configure 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. If you need to add custom services before you begin
configuring access rules, see Custom Services, page 87.
