have been playing with this and have these settings
For those struggling to set up openvpn on their VU+ box, this guide may be useful.
1. goto the client support pages of private internet access site and download the OpenVPN Configuration Files (Default)
2. from the zip file we need ca.crt crl.pem and any ovpn file
3. edit the name of the ovpn file to client.conf.
4. open the client.conf and modify the line "auth-user-pass" so it reads "auth-user-pass password.txt" (without the quotes)
5. create a password.txt file
6. put your PIA username and password on seperate lines into the password.txt file
7. place all 4 files (ca.crt, crl.pem, client.conf, password.txt) into the openvpn folder on your box (etc/openvpn)
8. reboot your vu+
9. start the service from the settings - network - openvpn
10. ssh to your vu+ and check the ip with this command wget -qO-
