Alternatively, the remote user uses SSL enabled browser session to communicate with the corporate network (shown as Private Network in the figure) FHRP (First Hop Redundancy Protocol): Usually, when a subscriber connects to an ISP using Wi-Fi router, he will have single point of failure. if the router fails, the connection to the Internet fails.

FHRP allows redundancy or a fail over mechanism, thus ensuring that there is no single point of failure for a subscriber to the Internet.
There are several protocol defined for FHRP, popular among these are: HSRP, VRRP, and GLBP.A VPN connections use 1) Encapsulation 2) Authentication, and 3) Data encryption. TCP/IP packets) is wrapped around by using encapsulation protocol such as GRE, IPsec, L2F, PPTP, or L2TP.
