Chapter 3 – Configure your MultiAccess
Setting Authentication
The Authentication menu displays two ports for the MA220, four ports for the model MA420 or eight ports
for the model MA820. The Authentication/Radius Client Configuration:POTS modem X fields allow
you to select and define certain user authentication details on a per port basis.
The Authentication Type option, on this menu, applies only to RAS, PPP, calls.
Please Note: When Modem Sharing, in Modem Setup, is configured to implement Radius Authentication
it will use the RADIUS Client details defined here to authenticate the user, regardless of how the
Authentication Type option on this menu is set.
When the authentication method is local, use the Local User menu to build a Database of user
credentials. The MultiAccess matches the credentials provided by the caller with the credentials listed in
the Local User Database. Additionally, local users can be configured for PPP call back.
When the Authentication Type is Radius, the MultiAccess sends the credentials provided by the caller to
the Radius Server for authorization.
For RAS calls, dial-in PPP, a second static IP address is needed in the Remote Host Address field. This
address is for the dial-in user, PPP peer. This address needs to be on the same subnet, network number,
as that of the MultiAccess.
When the authentication method is Radius, then the IP address and UDP port of the Radius Server and
Radius Accounting Server have to be entered and the Secret has to be entered.
Radius accounting begins after successful Radius authentication. Radius accounting summarizes the
time and date, duration, POTS port connected and the IP address given to the user for the call. Radius
accounting does not track the amount or type of data of the session or the places the user communicates
with.
The Secret is an MD5 encryption key used by both the Radius Server and Radius Client, MultiAccess. It
must be the same alphanumeric string, including case that is defined in the Radius Sever.
