In the following scenario, four HP R1 10/R120s provide a virtual private network (VPN) across
the Internet between corporate headquarters and three branch offices. The R1 10/R120 #1
creates secure VPN connections to R1 10/R120 #2, R1 10/R120 #3, and R1 10/R120 #4 at three
branch locations. The computers on each branch network can access the computers and
servers on the headquarters network.
