Chapter 11 Interfaces ports at the layer-2 (data link, MAC address) level. This provides wire-speed throughput but no security. Note the following if you are configuring from a computer connected to a lan1, lan2 or dmz port and change the port's role: 1 A port's IP address varies as its role changes, make sure your computer's IP address is in the same subnet as the ZyWALL's lan1, lan2 or dmz IP address. 2 Use the appropriate lan1, lan2 or dmz IP address to access the ZyWALL.

Table 49 Configuration > Network > Interface > Port Role LABEL DESCRIPTION LAN1/DMZ P2~P5 lan1 (LAN1) lan2 (LAN2) dmz (DMZ) These are physical Ethernet ports. 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). ZyWALL USG 20/20W User's Guide 221
