Chapter 7 Interfaces

7.1.3 What You Need to Do First

For IPv6 settings, go to the Configuration > System > IPv6 screen to enable IPv6 support on the ZyWALL first.

7.2 Port Role Screen

To access this screen, click Configuration > Network > Interface > Port Role. Use the Port Role screen to set the ZyWALL’s flexible ports as part of the lan1, lan2, ext-wlan or dmz interfaces. This creates a hardware connection between the physical ports at the layer-2 (data link, MAC address) level. This provides wire-speed throughput but no security.

Not the following if you are configuring from a computer connected to a lan1, lan2, ext-wlanor dmz port and change the port's role:

•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, ext-wlanor dmz IP address.

•Use the appropriate lan1, lan2, ext-wlanor dmz IP address to access the ZyWALL.

Physical Ports

Interfaces

The physical Ethernet ports are shown at the top and the Ethernet interfaces and zones are shown at the bottom of the screen. Use the radio buttons to select for which interface (network) you want to use each physical port. For example, select a port’s LAN radio button to use the port as part of the LAN interface. The port will use the ZyWALL’s LAN 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:

•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 Apply to save your changes and apply them to the ZyWALL.
