Select
SUA Only
if you have just one public WAN IP address for your
Prestige. The SMT uses Address Mapping Set 255 (menu 15.1 - see
section 8.3.1).
Select
None
to disable NAT.
Address
Mapping Set
When
Full Feature
is selected in the
NAT
field, configure address
mapping sets in menu 15.1. Select one of the NAT server sets (2-10) in
menu 15.2 (see the NAT chapter for details) and type that number here.
When
SUA Only
is selected in the NAT field, the SMT uses NAT server
set 1 in menu 15.2 (see the NAT chapter for details).
2
Metric The metric represents the “cost” of transmission for routing purposes.
IP routing uses hop count as the cost measurement, with a minimum of
1 for directly connected networks. Type a number that approximates the
cost for this link. The number need not be precise, but it must be
between 1 and 15. In practice, 2 or 3 is usually a good number.
2
Private This determines if the Prestige will include 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 will be
propagated to other hosts through RIP broadcasts.

6.1.2 IP Static Route Setup
Static routes tell the Prestige routing information that it cannot learn automatically through other means.
This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is
directly connected to a remote node.
Each remote node specifies only the network to which the gateway is directly connected and the Prestige
has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the
following figure through remote node Router 1. However, the Prestige is unable to route a packet to
