Configuring network gateways

Active and passive 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;.

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.
