Chapter 5 Virtual Private Networking This chapter describes how to use the virtual private networking (VPN) features of the ProSafe DGFV338. 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 ADSL port and the Ethernet port of the ProSafe DGFV338 can be configured for auto-rollover mode for increased system reliability (if both ports are configured) or, if only one of the ports is configured, they can be configured as either Dedicated ADSL or Dedicated Ethernet. This WAN mode choice then impacts how the VPN features must be configured. Table 5-1.
