VPN (Virtual Private Network) software allows users to connect to a remote computer network as if they were locally present. For example, VPN allows one to connect to a company network when working from home, telecommuting, or traveling. The remote network must have a VPN server to facilitate the connection.
In case you were wondering, VPN should work just fine with a network address translation (NAT) gateway to the Internet, which is common in many hotel and home router products.
Mac OS X 10.4.5 or later support:
Note:Multiple users behind the same NAT cannot use the same VPN server.
