OpenWRT configurations to run OpenVPN client | Private Internet Access - https://www.privateinternetaccess.com

This gist contains all the OpenWRT configuraion files needed to connect to Private Internet Access (PIA) VPN servers. The following files are included:

  • network: contains configuration to add a virtual network device (i.e. tun1366) and custom DNS servers
  • openvpn: OpenVPN configuration file to connect to PIA VPN servers
  • firewall: firewall configuration which passes all traffic through VPN and rejects any request when OpenVPN is down

NOTE: there are a number of other files required to be available under /etc/openvpn for this approach to work:

  • pia.auth: VPN credentials in two lines, first the username and the second the password
  • pia.ca.crt: certificate authority file
  • pia.crl.pem: certificate revocation list

For PIA the last two files can be downloaded here: https://www.privateinternetaccess.com/openvpn/openvpn.zip
