Unable o connect using openVPN PPTP to connect to VPN

Hi, thanks for the quick response. Sorry about calling it openvpn, it is a pptp connection to the VPN server. I have all the info I need to make the connection, the gateway, username, password and even enabled MMPE to be used as per the VPN providers information. It connects fine when the firewall is disabled, it only fails when the firewall is enabled (I have also used the same method and information to connect from Debian based distro’s no problem).
