Chapter 5 Virtual Private Networking This chapter describes how to use the virtual private networking (VPN) features of the VPN firewall. VPN tunnels provide secure, encrypted communications between your local network and a remote network or computer. Tip: When using dual WAN port networks, use the VPN Wizard to configure the basic parameters and them edit the VPN and IKE Policy screens for the various VPN scenarios. Dual WAN Port Systems The dual WAN ports in the VPN firewall can be configured for either Auto-Rollover mode for increased system reliability or Load Balancing mode for optimum bandwidth efficiency. This WAN mode choice then impacts how the VPN features must be configured. Refer to "Virtual Private Networks (VPNs)" on page C-10 for an overview of the IP addressing requirements for VPN in the two WAN modes. To aid in determining the addressing requirements for your VPN Tunnel in either rollover mode or load balancing mode, see Table 5-1. Table 5-1.
