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 then 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 rollover mode for increased system reliability by specifying the Broadband connection with the Dialup connection as backup. This WAN mode choice then impacts how the VPN features must be configured. Table 5-1.
