| VPDN offers customers several important features. For one thing, VPDN permits users to configure networks to take advantage of Internet Service Providers (ISPs) that tunnel the company's remote access traffic through the ISP cloud. This may take some of the tunneling burden away from the client's PC. The ISP now does the tunneling and puts the headers on packets. Remote offices or mobile users can connect to their home network using dial-up services of third parties, such as an ISP or Network Access Provider (NAP). Note that the provider would have to agree to forward the remote site's traffic to the company's home gateway.
