Chapter 13 Interfaces Each section in this screen is described below. Table 59 Configuration > Network > Interface > Port Role LABEL DESCRIPTION LAN1/WLAN/DMZ These are physical Ethernet ports. PX~P7 lan1 (LAN1) lan2 (LAN2) ext-wlan (WLAN) dmz (DMZ) These are Ethernet interfaces and the zone to which each belongs. Use the radio buttons to select for which interface (network) you want to use each physical port. For example, select a port's LAN1 radio button to use the port as part of the lan1 interface. The port will use the ZyWALL's lan1 IP address and MAC address. When you assign more than one physical port to a network, you create a port group. Port groups have the following characteristics: Apply Reset • There is a layer-2 Ethernet switch between physical ports in the port group. This provides wire-speed throughput but no security. • It can increase the bandwidth between the port group and other interfaces. • The port group uses a single MAC address. Click this button to save your changes and apply them to the ZyWALL. Click this button to change the port groups to their current configuration (last-saved values). 13.3 Ethernet Summary Screen This screen lists every Ethernet interface and virtual interface created on top of Ethernet interfaces. To access this screen, click Configuration > Network > Interface. Unlike other types of interfaces, you cannot create new Ethernet interfaces nor can you delete any of them. If an Ethernet interface does not have any physical ports assigned to it (see Section 13.2 on page 295), the Ethernet interface is effectively removed from the ZyWALL, but you can still configure it. Ethernet interfaces are similar to other types of interfaces in many ways. They have an IP address, subnet mask, and gateway used to make routing decisions. They restrict the amount of bandwidth and packet size. They can provide DHCP services, and they can verify the gateway is available. Use Ethernet interfaces to control which physical ports exchange routing information with other routers and how much information is exchanged through each one. The more routing information is exchanged, the more efficient the routers should be. However, the routers also generate more network traffic, and some routing protocols require a significant amount of configuration and management. The ZyWALL supports two routing protocols, RIP and OSPF. See 296 ZyWALL USG 100/200 Series User's Guide
