not be precise, but it must be between 1 and 16. In practice, 2 or 3
is usually a good number.
7. Private - This parameter determines if your 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.
8. RIP - This parameter determines how your Prestige handles RIP
(Routing Information Protocol), and the default is Both. If set to
Both, your Prestige will broadcast its routing table on the WAN,
and incorporate RIP broadcasts by the other router into its routing
table. If set to In Only, your Prestige will not broadcast its routing
table on the WAN; if set to Out Only, your Prestige will broadcast
its routing table but ignores any RIP broadcast packets that it
receives. If set to None, your Prestige will not participate in any
RIP exchange with other routers. Usually, you should leave this
parameter at its default of Both and let RIP propagate the routing
information automatically.

Static Route Setup
On a directly connected internet, RIP usually handles the routing
automatically. However, RIP cannot propagate across isolated
networks, as in the case before a connection is made between the two
subnetworks using one Class C IP address. Without a route, no
packets can be forwarded to their destinations. A static route is used to
resolve this problem by providing your Prestige with some static routing
information. As a matter of fact, when you configure the Internet Access
