DESCRIPTION

LAN1/WLAN/DMZ

These are physical Ethernet ports.

PX~P7

 

 

 

lan1 (LAN1)

These are Ethernet interfaces and the zone to which each belongs. Use the

ext-wlan (WLAN)

radio buttons to select for which interface (network) you want to use each

dmz (DMZ)

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:

 

• 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.

10.4 The Ethernet Summary Screen

This screen lists every Ethernet interface and virtual interface created on top of Ethernet interfaces. To access this screen, click Network > Interface > Ethernet.

Unlike other types of interfaces, you cannot create new Ethernet interfaces nor can you delete any of them. If you do not assign any physical ports to one of the lan1, ext-wlan, or dmz Ethernet interfaces (see Section 10.3 on page 205), 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 Chapter 13 on page 287 for background information about these routing protocols.
