Configure PPP Security
The IOLINK-130 provides support for both PAP and CHAP PPP
security authentication. An outgoing user name, PAP password , and
CHAP secret are defined that the IOLINK-130 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-130 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-130 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-130s that have security levels set.
Default user name is the same as the default device name.
Default PAP password and CHAP secret are both set to “none”.
The complete 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-130 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-130, an entry for each
remote site PPP router that may be connected to this IOLINK-130 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.
