4Configuring the FirewallThis chapter contains information about configuring the firewall properties of theCisco RV120W and includes the following sections:• Cisco RV120W Firewall Features, page 65• Configuring Access Rules, page 67• Configuring Attack Prevention, page 71• Configuring Content Filtering, page 72• Configuring URL Blocking, page 74• Configuring Port Triggering, page 75• Configuring Port Forwarding, page 76• Configuring a DMZ Host, page 80• Configuring Advanced Firewall Settings, page 80• Firewall Configuration Examples, page 87Cisco RV120W Firewall FeaturesYou can secure your network by creating and applying access rules that theCisco RV120W uses to selectively block and allow inbound and outbound Internettraffic. You then specify how and to what devices the rules apply. You canconfigure the following:• Services or traffic types (examples: web browsing, VoIP, other standardservices and also custom services that you define) that the router shouldallow or block.• Rules for outbound (from your LAN to the Internet) or inbound (from theInternet to your LAN) traffic.Cisco RV120W Administration Guide 65
Configuring the FirewallCisco RV120W Firewall Features4• Schedules as to when the router should apply rules.• Keywords (in a domain name or on a URL of a web page) that the routershould allow or block.• MAC addresses of devices whose inbound access to your network therouter should block.• Port triggers that signal the router to allow or block access to specifiedservices as defined by port number.• Reports and alerts that you want the router to send to you.You can, for example, establish restricted-access policies based on time-of-day,web addresses, and web address keywords. You can block Internet access byapplications and services on the LAN, such as chat rooms or games. You can blockjust certain groups of PCs on your network from being accessed by the WAN orpublic network.Inbound (Internet to LAN) rules restrict access to traffic entering your network,selectively allowing only specific outside users to access specific local resources.By default, all access from the insecure WAN side is blocked from accessing thesecure LAN, except in response to requests from the LAN or DMZ. To allowoutside devices to access services on the secure LAN, you must create a firewallrule for each service.If you want to allow incoming traffic, you must make the router's WAN port IPaddress known to the public. This is called “exposing your host.” How you makeyour address known depends on how the WAN ports are configured; for theCisco RV120W, you may use the IP address if a static address is assigned to theWAN port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name canbe used.Outbound (LAN to Internet) rules restrict access to traffic leaving your network,selectively allowing only specific local users to access specific outside resources.The default outbound rule is to allow access from the secure zone (LAN) to theinsecure WAN. To block hosts on the secure LAN from accessing services on theoutside (insecure WAN), you must create a firewall rule for each service.Cisco RV120W Administration Guide 66
