====== PFSense - VPN - Use ExpressVPN - Configure Firewall ======

Now that the tunnel is online, you need to tell all of your traffic to be NAT’d properly.

===== Configure NAT =====

<WRAP info>
**NOTE:** This will be using the **Manual Outbound NAT rule generation**.

An Alternative method is using the **Hybrid Outbound NAT rule generation**.

See [[PFSense:Use ExpressVPN:Configure Firewall:Hybrid Outbound NAT rule generation|Hybrid Outbound NAT rule generation]]

</WRAP>


Navigate to **Firewall -> NAT -> Outbound**.

  * Select **Manual Outbound NAT rule generation**.
  * Press **Save**.

Then multiple rules will appear. (Usually 4 rules).

Duplicate each of these rules exactly, but change their interface to the ExpressVPN or OpenVPN interface, clicking Save after each rule is duplicated.

Against the rule **Auto created rule - LAN to WAN**, click on the icon on the right side that looks like two pages (a square overlapping another square).

In the window that pops up:, the only selection you will be changing is the **Interface” section**.

  * Interface:  Click the drop-down and change from **WAN** to the name of the Interface you created previously, in this case **VPN_WAN**.
  * Click **Save**.

  * Repeat this for the other interfaces.
  * Click **Apply Changes** at the top.


The result should be similar to this (the interface names may differ depending on what you used):

===== Configure Firewall Rules =====

Create a rule to redirect all local traffic through the ExpressVPN gateway you previously created.

Navigate to **Firewall > Rules**:

Click on **LAN**.

Click the **Add** button with the up arrow (the far left button).

Enter the following:

In **Edit Firewall Rule**:

  * Action:  **Pass**.
  * Disabled:  **Not Checked**.
  * Interface:  **LAN**.
  * Address:  **IPv4**.
  * Protocol:  **Any**.

In **Source**:

  * Source:  Select **Single host or alias**; and type the name of the host or alias that should use the VPN.

in **Destination**:

  * Destination:  **any**.

In **Extra Options**:

  * Log:  **Not Checked**.
  * Description:  Enter something meaningful to you.  For example **LAN TRAFFIC –> EXPRESSVPN**.

Click the blue **Display Advanced** button.

In **Advanced Options**:

  * Gateway:  **VPN_WAN**.
  * Leave everything else.
  * Click **Save**.

===== Complete =====

You are finished! 

You should now start to see traffic flowing through your new rule you created, confirming that the traffic is moving through the ExpressVPN tunnel you created.
