Network Address With Network Address Translation (NAT), the router translations an
Translation Internet protocol address used within one network (for example, a
private IP address used in a local network) to a different IP address
known within another network (for example, a public IP address
used on the Internet). NAT is available when the device is in routing
mode.
Choose None to disable NAT.
Choose SUA Only if you have a single public IP address. SUA
(Single User Account) is a subset of NAT that supports two types of
mapping: Many-to-One and Server.
Choose Full Feature if you have multiple public IP addresses. Full
Feature mapping types include: One-to-One, Many-to-One (SUA/
PAT), Many-to-Many Overload, Many- One-to-One and Server.
After you select Full Feature, you must configure at least one
address-mapping set.
Metric ( This field sets this route's priority among the routes the Business
Secure Router uses.
The metric represents the cost of transmission. A router determines
the best route for transmission by choosing a path with the lowest
cost. RIP routing uses hop count as the measurement of cost, with
a minimum of 1 for directly connected networks. The number must
be between 1 and 15; a number greater than 15 means the link is
down. The smaller the number, the lower the cost.
Private (PPPoE and This parameter determines if the Business Secure Router includes
PPPoA only) the route to this remote node in its RIP broadcasts. If set to Yes,
this route is kept private and not included in RIP broadcast. If No,
the route to this remote node is propagated to other hosts through
RIP broadcasts.
