Setting Firebox Interface Speed and Duplex2 Click Add.The Add Route dialog box appears.3 Select Host IP from the drop-down list.4 In the Route To text box, type the host IP address.5 In the Gateway text box, type the IP address of the router.Make sure that you enter an IP address that is on one of the same networks as the Firebox.6 Click OK to close the Add Route dialog box.The Setup Routes dialog box shows the configured host route.7 Click OK again to close the Setup Routes dialog box.Setting Firebox Interface Speed and DuplexYou can configure the speed and duplex parameters for Firebox® interfaces to automatic or manual configuration.We recommend you set the speed and duplex parameters to match the device the Fireboxconnects to. Use the manual configuration option when you must override the automatic Firebox interfaceparameters to operate with other devices on your network.1 Select Network > Configuration. Click the interface you want to configure, and then clickConfigure.2 Click Advanced Settings.The Advanced Settings dialog box appears.3 From the MTU value control, select the maximum packet size, in bytes, that can be sent through theinterface.If you use PPPoE, you must change this value to 1492, or the MRU supported by your ISP. If you do not use PPPoE,we do not recommend that you change the MTU value.4 From the Link Speed drop-down list, select Auto Negotiate if you want the Firebox to select thebest network speed. You can also select one of the half-duplex or full-duplex speeds that you knowis compatible with your equipment.5 Click OK to close the Advanced Settings dialog box. Click OK again to close the NetworkConfiguration dialog box.Configuring Related HostsIn a drop-in configuration, the Firebox® is configured with the same IP address on each interface. Thedrop-in configuration mode distributes the network’s address range across the Firebox interfaces.Related hosts are sometimes required when you have configured your Firebox in drop-in mode andautomatic host mapping is not functioning correctly. This sometimes happens because of interferencewith the Firebox trying to discover devices on an interface. When this occurs, turn off automatic hostmapping and add related host entries for computers that share a network address with the Firebox. Thiscreates a static routing relationship between the related host IP address and the interface designatedUser Guide 111
