Example VPN configuration 3: create Access rules

Create a rule to allow specific users access to internal networks after having authenticated.

The authentication connection from VPN clients is allowed in the Firewall Template. Authentication is always required to establish a VPN tunnel. VPN client connections are matched based on Source, Destination, and Service like any other traffic. The example rule matches only specific users and only after the users have already successfully authenticated. We recommend always adding the authentication requirement to rules that are specific to VPN clients.

After the VPN tunnel is established, any connection from the VPN clients to the internal network is matched against the Access rules as usual. The example rule that is created here allows these connections.

Note: This configuration scenario does not explain all settings related to VPN Access rules.
