2.4.3.2 - Configure PPP Security

The PPP IOLINK-520 & IOLINK-PRO provide support for both PAP and CHAP
security access authentication. An outgoing user name, PAP password, and CHAP secret
are defined that the IOLINK router will use when responding to an authentication request
from a remote site PPP router.
The cold start defaults for the security user name and passwords are as follows.
These defaults will exist when the IOLINK router is first started before and
configuration is entered, and after a Full Reset has been performed. These default
values are also set when the IOLINK router is placed in TFTP Network load mode for
upgrading the operating software via TFTP transfers. Care should be taken when
upgrading a group of IOLINK routers that have security levels set.
Default outgoing user name for each remote site when it is defined is the same as
the default device name. Default PAP password and CHAP secret are both set to
“BRIDGE”.
The complete password security configuration for both incoming and outgoing calls is
defined within the Security menu of the WAN set-up section.

The security level defines the type of security that this IOLINK router
will request when a remote site PPP router attempts to establish a PPP
connection. The security may defined as none, PAP, or CHAP.
When a security level is defined on this IOLINK router, an entry for each remote site PPP
router that may be connected to this IOLINK router must be placed in the security
database. The security database is used to store the user names and passwords of the
remote site PPP routers.
