Serial Port Profiles
Remote Access (PPP) Profile
Overview
The
Remote Access (PPP)
profile configures a serial port to allow a remote user to establish a PPP
connection to the IOLAN’s serial port. This is typically used with a modem for dial-in or dial-out
access to the network or a wireless WAN card.
Functionality
There are two options for PPP user authentication:
1.
You can configure a specific user/password and a specific remote user/password per a serial port.
2.
You can create a secrets file with multiple users and their passwords that will globally
authenticate users on all serial ports.
You can use configure PPP authentication in the configuration or in the secrets file, but not both.
If you want to use a secrets file, you must download the secrets file to the IOLAN for CHAP or PAP
authentication; the files must be downloaded to the IOLAN using the names
chap-secrets
and
pap-secrets
, respectively. The file can be downloaded to the IOLAN under the
Custom Files
option by selecting the
Download Other File
parameter.
In the
Remote Access (PPP)
profile, you must also specify the
Authentication
option as
PAP
or
CHAP
on the
Authentication
tab, but must leave the
User
,
Password
,
Remote
User
, and
Remote
Password
fields blank.
An example of the CHAP secrets file follows:
# Secrets for authentication using CHAP
# client server secret acceptable local IP addresses

An example of the PAP secret file follows:
# Secrets for authentication using PAP
# client server secret acceptable local IP addresses
