These are Ethernet interfaces. To add a physical port to a

Interface (ge1,

representative interface, drag the physical port onto the

ge2, ge3, ge4,

corresponding representative interface.

These are the physical ports as they appear on the front panel of the

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 280), 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 16 on page 363 for background information about these routing protocols.
