Hi Robbie
Very sorry to hear you are having issues with the VPN. I would be unsure of what is going wrong there, it sounds OK to me, but I am not expert when it comes to VPNS. The only team that would really deal with this are our Enhanced IT Support Team. They are available on 0800 500 247, so I would recommend giving them a call and the ywould be able to go into it in more depth. Otherwise, someone else on the forum may have VPN expertise and may be able to assist you with this also 
Regards
Ryan
