Setting Authentication
Authentication Type option defines where the database of user credentials reside. Local Authentication
refers to the Local User Database on the MultiAccess. Radius Authentication refers to a user database
controlled by a Radius Server outside the MultiAccess.
If a Radius Server is used for authentication, then the server has to be configured to receive requests
from the MA100-1M.
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 server. This address needs to be on the same subnet, network
number as that of the MultiAccess.
Remote Host Address is not used if the modem sharing is set for authentication..
Radius Client Setup points to the Radius Server when the Authentication is Radius.
