In the following scenario, four HP R110/R120s provide a virtual private network (VPN) across
the Internet between a headquarters and three branch offices. The R110/R120 #1 forms secure
VPN tunnel connections to R110/R120 #2, R110/R120 #3, and R110/R120 #4 at three branch
locations. The computers on each branch network can access the computers and servers on the
headquarters network.
