DNS Client
Figure 37: DNS Client
This menu allows you to display and configure various DNS client fields.
The Resolution Order selector determines the order of sources for resolving domain
names into IP addresses. The Hosts file /etc/hosts can be populated with frequently
used, but unchanging addresses. DNS refers to any configured DNS servers.
The DNS servers fields allow you to specify, in order, the serves to resolve from.
The Search domains fields allow you to specify the domain name of the network the
router is located within. This allows short names relative to the local domain to be
used. If you do not specify a domain name the router will try and extract this
information from the host addresses.
Host Addresses
Figure 38: Host Addresses
This menu allows you to display and configure host addresses. Host addresses are
useful when a non-changing IP address is often used or when DNS is not configured.
Follow the Add a new host address link to add an address.
End To End Backup
End To end backup is method of using two interfaces to ensure a reliable end to end
connection between two routers using alternate routing, without the need to configure
routing protocols.
The two interfaces are assigned as a primary:secondary backup pair. The primary
interface serves as the gateway. If connectivity to the target is lost from the primary
interface, traffic is migrated to the secondary interface. When connectivity is restored
on the primary path, traffic will be restored to it.
