My school is Cockermouth School, and it's a bit damp up here...
Anyhow, a local company's been washed out and they would like to use our (perfectly fine

) internet connection to give them access via thier own laptops to thier network in another part of the country.
The laptops are already set up and work fine through any home broadband connection, but I really don't think they'll work through our proxies.
In addition to our ISP connection, I also have a single unfiltered connection with a public IP address. Never having set up a VPN before, what exactly do I need to hang off this in order to get it working ? First thoughts here would be a PC running a software router. Would this suffice ?
Help !
Regards all
Adrian
