These firewalls can easily be configured with a table of addresses which are mainly responsible for the characterisation of the packets.
The term VPN stands for Virtual private Network. The VPN mainly provides well controlled connectivity while using a public network which can be the Internet. The IP tunnel is the main concept on which the VPN is based. This actually facilitates virtual point to point link between different arbitrary of a specified network. Though the IP address is usually provided at the end of the router, the virtual link is usually created at the entrance of the specific tunnel. Packets usually get encapsulated with the IP datagram while being sent from the router. Though the source address lies on the encapsulated router, the destination address is present in the IP header.
Many VPN users use different types of hardware firewalls to enrich their online privacy as well as security too.
