Configuring network gateways
Gateways are hosts that connect Local Area Networks (LANs) together. If you want
to access a host which isn’t on your local network you will be connected via a
gateway. Gateways route data via other gateways until the destination local network
is reached. There are three types:
• Default - this is a gateway which provides general access beyond your local
network.
• Host - this a gateway reserved for accessing a specific host external to your local
network.
• Network - this is a gateway reserved for accessing a specific network external to
your local network.
The unit allows you enter a maximum of twenty gateways.
Particularly useful when checking routes to/from gateways is the show routes
command;.
Active and
passive
gateways
The unit supports both active and passive gateways. The default is active. Definitions
of these types are as follows:
Active gateway: a gateway which is temporarily listed in the unit’s routing table
(while RIP packets are received). If the unit detects that the gateway
is no longer operating (no RIP packets received) it will be deleted
from the routing table.
Passive gateway: a gateway which is permanently listed in the unit’s routing table. It
is thus always available.
See the following for how to configure gateways:
• Adding a gateway on page 59
• Deleting a Gateway on page 60.
