There is a special NIC I can get for the server that is about £60, allows access to the machine even while it is off, called a "remote access card" I think, would probably save needing to VPN as it's a web based access system
Might go down that route if I can't get the router VPN stuff sorted out, would rather avoid as it would mean taking another cable, it's a new Netgear made Virgin superhub and annoyingly I'm at the parents for the rest of the week on holiday.... hopefully relaxing
