Security
The router provides a number of means of providing security on incoming and outgoing
traffic on a network. These methods include access password authentication, firewall
limiting access to only designated device addresses, private network address translation
(NAT) and filtering for both incoming and outgoing traffic.
Configure PPP Security
The PPP router provides support for both PAP and CHAP security access authentication.
An outgoing user name, PAP password, and CHAP secret are defined that the 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 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 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 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.

Ä Security Level
The security level defines the type of security that this 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 router, an entry for each remote site PPP router that
may be connected to this 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.
