Configuring PPP Dial On Demand
Configuring PPP Dial On Demand
The IOLAN can be configured to access remote networks via modems connected to the serial
interface of the IOLAN. By configuring the IOLAN for the
Remote Access (PPP) profile, data that
is destined for the remote network will initiate a modem connection to the remote network to route
the data to its appropriate destination.

configuration
If you want to configure a serial port to use PPP dial on demand, do the following:
1. Create an entry for the modem and its initialization string ( Serial , Advanced , Modems tab).
2. Set the serial port to Remote Access (PPP) .
3. In Remote Access (PPP) , select the Advanced tab. Enable the Connect option and select Dial
Out . Set the Modem parameter to the modem you just added. Enter the Phone number that the
modem will be calling.
4. Still on the Advanced tab, set the Idle Timeout parameter to a value that is not zero (setting this
value to zero creates a permanent connection).
5. On the General tab, enter one of the following:
z A Local and/or Remote IPv4 Address
z A Local and/or Remote IPv6 Interface Identifier
Note that this IP address or interface identifier should be on its own unique network; that is, not
part of the local or remote networks.
In this example, the local network has an IPv4 address of 172.16.0.0/16 and the remote network
has an IPv4 address of 204.16.0.0/16, so we arbitrarily assigned the PPP
IPv4 Local IP Address
as 195.16.20.23 and the PPP IPv4 Remote IP Address as 195.16.20.24 .
