Configuring NetworkingConfiguring Routing2STEP 7STEP 8STEP 9In the IP Subnet Mask field, enter the IPv4 Subnet Mask for the destination host ornetwork. For Class C IP domains, the Subnet Mask is 255.255.255.0.From the Interface drop-down menu, choose the physical network interfacethrough which this route is accessible (WAN or LAN).In the Gateway IP Address field, enter the IP Address of the gateway throughwhich the destination host or network can be reached. If this firewall is used toconnect your network to the Internet, then your gateway IP is the firewall's IPaddress. If you have another router handling your network's Internet connection,enter the IP address of that router instead.STEP 10 In the Metric field, enter a value between 2 and 15 to define the priority of theroute. If multiple routes to the same destination exist, the route with the lowestmetric is chosen.STEP 11 Click Save.Configuring Dynamic RoutingRIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP)that is commonly used in internal networks. It allows the Cisco RV120W toexchange its routing information automatically with other routers, and allows it todynamically adjust its routing tables and adapt to changes in the network.NOTERIP is disabled by default on the Cisco RV120W.To configure dynamic routing:STEP 1STEP 2Choose Networking > Routing > Dynamic Routing.To configure how the firewall sends and receives RIP packets, choose the RIPdirection:• None—The firewall neither broadcasts its route table nor does it accept anyRIP packets from other routers. This option disables RIP.• In Only—The firewall accepts RIP information from other router, but doesnot broadcast its routing table.Cisco RV120W Administration Guide 38
