WebIPsec provides an easy mechanism for implementing Virtual Private Network (VPN) for such institutions. VPN technology allows institution’s inter-office traffic to be sent over public Internet by encrypting traffic before entering the public Internet and logically separating it from other traffic. WebIPsec is used in tunnel mode or transport mode. Security gateways use tunnel mode because they can provide point-to-point IPsec tunnels. ESP tunnel mode encrypts the entire packet, including the original packet headers. son of galleon
