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

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
