# Define Authentication options for Firewall Access rules

The Authentication options define which users can authenticate and the type of authentication required.

##

A mobile VPN always requires some form of authentication, but you can also add an authentication requirement to non-VPN rules.

The authentication requirements are configured in the Authentication cell. The cell accepts User and User Group elements to define the end users who are allowed to make connections allowed by the rule, and Authentication Method elements to define the type of authentication required for connections that match the rule.

If the authentication fails, the connection is discarded. If the authentication succeeds, the connection is allowed through.
