 ===== Assign Individual IPs to OpenVPN users =====
-At this point, in order to implement the scheduling created in the Firewall Rules, it is necessary to assign a very specific static IP address of the VPN tunnel to the users we want to limit.

   * Navigate to **VPN -> OpenVPN -> Client Specific Overrides**.
-  * Click the **Add** button
+  * Click the **Add** button.
 In the configuration screen that will appear, it will be sufficient to configure only 2 items:
-  * Common Name: **The name of the VPN user**.
+  * Server List:  **Select the OpenVPN Server to associate this with**.
-  * Advanced:  Insert the following string **ifconfig-push [IP_TUNNEL] [NETMASK]**.
+  * Common Name:  **The name of the VPN user**.
-    * Where IP_TUNNEL will be the IP address of the tunnel that we would like to be assigned to the user.

+===== Create Firewall Rules =====
+Navigate to **Firewall -> Rules**.
+Select the **OpenVPN** interface.
+Click **Add** button to create a new rule to be placed at the top.
+  * Action:  **Pass**.
+  * Interface:  **OpenVPN**.
+  * Address Family:  **IPv4**.
+  * Protocol:  **Any**.
+  * Source:  **Single host or alias** **10.20.30.69**.  This is the IP address belonging to the VPN Tunnel network defined previously and assigned to the user concerned.
+  * Destination:  **Single host or alias** **192.168.1.123**.  The IP address of the server to which we want to restrict the user’s connection.
+  * Advanced Options: In the Schedule, Select the Schedule created previously.
+<WRAP info>
+**NOTE:**  This allows a user who connects to the VPN with the IP address of the Tunnel 10.20.30.69 to access only the server 192.168.1.123 during the time range established in the scheduling.
+Repeat the procedure for each user to whom you want to grant access to the server at a certain time range.
+</WRAP>
+----
+To prevent the user from accessing other devices on the network, an additional rule that blocks access to everything should be placed UNDER the previously created access rules and associated with it.
+  * Navigate to **Firewall -> Rules**.
+  * Action:  **Block**.
+  * Interface:  **OpenVPN**.
+  * Address Family:  **IPv4**.
+  * Protocol:  **Any**.
+  * Source:  **Single host or alias** **10.20.30.69**.  This is the IP address belonging to the VPN Tunnel network defined previously and assigned to the user concerned.
+  * Destination:  **LAN net**.
+<WRAP info>
+**NOTE**:  The Firewall Rules will show under the **Schedule** column a symbol which will change color between Green and Yellow.
+  * Green indicates this is in scheduling range and therefore there will be access.
+  * Yellow indicates this is out of the scheduling range and therefore there will not be access.
