Select the 

6. 

Authentication Type to be applied to the dial-in connection.

The ECS0016 uses authentication to challenge Administrators who  

•

    dial-in to the gateway. (For dial-in access, the username and  
    pass word received from the dial-in client are verified against the  
    local authentication database stored on the ECS0016).   The  
    Administrator must also have their client PC / workstation configured  
    to use the selected authentication scheme. 

Select 

7. 

PAP, CHAP, MSCHAPv2 or None and click Apply.

 - With this selection, no username or password authentication  

    is required for dial-in access. This is not recommended. 

Password Authentication Protocol (PAP) is the usual method  

    of user authentication used on the internet: sending a username and  
    password to a server where they are compared with a table of  
    authorized users. Whilst most common, PAP is the least secure of  
    the authentication options. 

 Challenge Handshake Authentication Protocol (CHAP) is  

    used to verify a user’s name and password for PPP Internet  
    connections. It is more secure than PAP, the other main  
    authentication protocol. 

  - Microsoft Challenge Handshake Authentication  

    Protocol (MSCHAP) is authentication for PPP connections between  
    a computer using a Microsoft Windows operating system and a  
    network access server. It is more secure than PAP or CHAP, and is  
    the only option that also supports data encryption
