ROUTING
Add/Edit Route: Adds a new route to the IP routing table or edits an existing route.
Destination IP: The IP address of packets that will take this route.
Gateway:Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.0 implies there is
no next hop, and the IP address matched is directly connected to the router on the interface specified:
LAN or WAN.
Metric: The route metric is a value from 1 to 16 that indicates the cost of using this route. A value of 1
is the lowest cost, and 15 is the highest cost. A value of 16 indicates that the route is not reachable
from this router. When trying to reach a particular destination, computers on your network will select
the best route, ignoring unreachable routes.
Interface: Specifies the interface -- LAN or WAN -- that the IP packet must use to transit out of the
router, when this route is used.
Clear: Re-initialize this area of the screen, discarding any changes you have made.
Routes List: The section shows the current routing table entries. Certain required routes are

can be deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and
the "Edit Route" section is activated for editing. Click the Enable checkbox at the left to directly
activate or de-activate the entry.
