PPP Port Dial-On-Demand = [enabled l disabled]
The RouteFinder can be setup to bring down the connection on the WAN link when there is no real data traffic
on the line. The RouteFinder will then automatically bring up the WAN link when there is a need for data to
get across.
NOTE: The Novell IPX and SPX protocols generate some "session alive" packets. The RouteFinder tries to
"spoof" these packets so that they don't keep the links up. The Novell File Server generated "Serialization"
packets are also not transmitted across the WAN links for the same reason. Periodic broadcast of IPX RIP
and SAP packets is also avoided on dial-on-demand links. In case of IP,RIP routing is entirely disabled and
you will need to use default or static routes to support IP routing on the specified port.
Routing Information Protocol (RIP) is a protocol used among routers to exchange routing table information.
RIP is the most common protocol used in both IP and IPX networks. RIP is also used internally by client
workstations in IPX networks to obtain routes (shortest or otherwise) to any distant network.
PPP Port Hangup After = [decimal integer in minutes]
When a PPP port is setup for "Dail-On-Demand", the RouteFinder will bring the WAN communication device
down (sets the DTR signal low) when no data is to travel across this link. The RouteFinder waits for this
amount of time before it brings down the connection.
Recommended value: 3 minutes
Remote Port Setup
The RouteFinder can dial into another LAN and access its resources (Remote Access or RAS) as well as
connecting to another PPP compliant router. This option is to set up the kind of PPP peer that the chosen link
goes to.
Client Only - Enable this option if the PPP peer is a dial-up client. If you choose this option, you can save on
IP addresses since the client's IP address will belong to the LAN network. Also, the IP address of the router's
WAN port will be the same as the IP address of its LAN port.
Client or LAN - Enable this option if the PPP peer can be a dial-up client or another router. Note, that it is
possible to use a dial-up client even if you have configured the port as a client or LAN. But, if the port is
configured as a Client Only port, it is possible to achieve a definite savings in the number of IP addresses
used.
