I've been researching VPN's, and I was wondering hoe to set one up without expensive hardware. The VPN will be used to connect less than 4 people to the network at work. I would like to be able to let them acsess the network from anywhere in the country. I've seen OmniVPN, but I was wondering about any software alternitives. Would I also need any specific harware to use software vpn, or wouldt the plain old router/switch be just fine?
