How to use pfSense with FoxyProxy OpenVPN

This guide makes the following assumptions:

  1. Your pfSense is set up properly and you can get proper Internet and LAN connectivity on it.
  2. Your version of pfSense is newer than 2.1.1
  3. You want to route ALL of your Internet traffic over the VPN.

Replace all instances of “SERVERNAME” with your actual FoxyProxy server name – for example, if your VPN server is someserver.getfoxyproxy.org then you would replace SERVERNAME with “someserver” (without quotes).

Test

Test that pfSense is connected to the VPN server by going to https://getfoxyproxy.org/geoip. If you are connected through VPN, the page reports the IP address and location of the VPN server. If it does not display that, try rebooting pfSense, wait for it to come back up fully, and visit https://getfoxyproxy.org/geoip again.
