Chapter 11 Interfaces Table 55 Configuration > Network > Interface > Ethernet > Edit (continued) LABEL DESCRIPTION Interface Type This field is read-only. Internal is for connecting to a local network. Other corresponding configuration options: DHCP server and DHCP relay. The ZyWALL automatically adds default SNAT settings for traffic flowing from this interface to an external interface. External is for connecting to an external network (like the Internet). The ZyWALL automatically adds this interface to the default WAN trunk. Interface Name Port Zone MAC Address Description IP Address Assignment Get Automatically For General, the rest of the screen's options do not automatically adjust and you must manually configure a policy route to add routing and SNAT settings for the interface. Specify a name for the interface. It can use alphanumeric characters, hyphens, and underscores, and it can be up to 11 characters long. This is the name of the Ethernet interface's physical port. Select the zone to which this interface is to belong. You use zones to apply security settings such as firewall, IDP, remote management, anti-virus, and application patrol. This field is read-only. This is the MAC address that the Ethernet interface uses. Enter a description of this interface. It is not used elsewhere. You can use alphanumeric and characters, and it can be up to 60 characters long. These IP address fields configure an IP address on the interface itself. If you change this IP address on the interface, you may also need to change a related address object for the network connected to the interface. For example, if you use this screen to change the IP address of your LAN interface, you should also change the corresponding LAN subnet address object. This option appears when Interface Properties is External or General. Select this to make the interface a DHCP client and automatically get the IP address, subnet mask, and gateway address from a DHCP server. Use Fixed IP Address IP Address Subnet Mask Gateway You should not select this if the interface is assigned to a VRRP group. See Chapter 39 on page 693. This option appears when Interface Properties is External or General. Select this if you want to specify the IP address, subnet mask, and gateway manually. Enter the IP address for this interface. Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates what part of the IP address is the same for all computers in the network. This option appears when Interface Properties is External or General. Enter the IP address of the gateway. The ZyWALL sends packets to the gateway when it does not know how to route the packet to its destination. The gateway should be on the same network as the interface. ZyWALL USG 50 User's Guide 225
