Accepted PPP 
Authentication 

(only relevant to 

Link with PPP 

Protocol) 

 (Password 

PPP supports two types of security systems: 
CHAP is a type of authentication in which the authentication agent 

(typically a network server) sends the client program a key to be used 

to encrypt the username and password. This enables the username and 

password to be transmitted in an encrypted form to protect them 
against hackers. 
PAP is the most basic form of authentication, in which a user's name 

and password are transmitted over a network and compared to a table 
of name-password pairs. Typically, the passwords stored in the table 

are encrypted. The main weakness of PAP is that both the username 

and password are transmitted in an unencrypted form. 

Accessible 

Stations/Nets 

Defines parameters which limit public access to the network. Access 

can be allowed for all stations/nets, only certain stations/nets, or only 
stations/nets which are static. When the access mode is 'limited', use 

the access list to define which stations/nets have access. 

User Access 

Profiles (only 

relevant to Link 
with PPP 

Protocol) 

View and modify user access profiles in the access control users list. 

The list contains user names, security parameters and dialback options.
