Chapter 5 - Configuring Networking
Dummy Interface
Figure 38: Dummy Interface
This menu allows you to configure a dummy interface. Normally the router is
reachable on any of its interface addresses, whether the interface is active or not.
When OSPF and link detection is used, inactive interfaces are not advertised to the
network and thus not reachable. A dummy interface is always advertised and thus
reachable.
Routing And Gateways
Figure 39: Routing And Gateways
This menu allows you to configure the default gateway address and static routes.
Static routes specify a way to forward subnets of traffic that cannot be associated with
the subnets of configured interfaces. The gateway address is the address that is used
to forward traffic that can not be routed to configured interfaces or to static routes.
This menu also allows user to convert manually entered static routes to permanently
configured static routes.
Default Route Table
The first table of this menu configures the default gateway address.
Note: Don't configure a default gateway if you plan to provide one from a WAN,
PPPoE or modem interface. Don't manually configure configure the default gateway
in the /etc/network/interfaces file, configure the default gateway from this menu.
