Adding Secondary Networks3 Type the IP address and default gateway for the interface. Click OK.When you type an IP address, type all the numbers and the periods. Do not use the TAB or arrow key.After you configure a second external interface, multiple WAN configuration options appear in the NetworkConfiguration dialog box.4 Select the procedure you want to use to control traffic among multiple external interfaces.These three procedures are described above.5 In the WAN Ping Address dialog box, double-click in the Ping Address column to add an IPaddress or domain name for each external interface. We recommend that you use the IP address ofa computer external to your organization.When an external interface is active, the Firebox pings the IP address or domain name you set here each 20 secondsto see if the interface is operating correctly. If there is no response after three pings, the Firebox starts to use thesubsequent configured external interface. It then starts to ping the WAN ping address you set for that interface tocheck for connectivity.6 Click OK. Save your changes to the Firebox.Adding Secondary NetworksA secondary network is a network that shares one of the same physical networks as one of the Firebox®interfaces. When you add a secondary network, you make (or add) an IP alias to the interface. This IPalias is the default gateway for all the computers on the secondary network. The secondary networktells the Firebox that there is one more network on the Firebox interface.User Guide 105
