Another issue I found, could not connect for the life of me, following PureVPN steps and tips here, then spoke to support, turns out dedicated IP hosts dont work with OVPN, only PPTP / L2TP. As soon as I changed to one of PureVPNs "normal" public hosts it connected instantly. Im using PF 2.4.3 with custom options in VPN client settings as below:
verb 5;
auth-nocache;
remote-cert-tls server;
comp-lzo
