Chapter 13 Interfaces cannot change the MTU. The virtual interface uses the same MTU that the underlying interface uses. Unlike other interfaces, virtual interfaces do not provide DHCP services, and they do not verify that the gateway is available. 13.11.1 Virtual Interfaces Add/Edit This screen lets you configure IP address assignment and interface parameters for virtual interfaces. To access this screen, click an Add icon next to an Ethernet interface, VLAN interface, or bridge interface in the respective interface summary screen. Figure 290 Configuration > Network > Interface > Add Each field is described in the table below. Table 84 Configuration > Network > Interface > Add LABEL DESCRIPTION Interface Properties Interface Name This field is read-only. It displays the name of the virtual interface, which is automatically derived from the underlying Ethernet interface, VLAN interface, or bridge interface. Description 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. IP Address Assignment IP Address Enter the IP address for this interface. Subnet Mask 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. Gateway 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 300 User's Guide 363
