What You Need To Do First; Port Role Screen - ZyXEL Communications 310 User Manual

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-wlan or
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-wlan or dmz IP address.
• Use the appropriate lan1, lan2, ext-wlan or dmz IP address to access the ZyWALL.
Figure 73 Configuration > Network > Interface > Port Role (110)
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.
