Chapter 5 Virtual Private Networking This chapter describes how to use the VPN features of the FVM318 firewall. VPN tunnels provide secure, encrypted communications between your local wireless and Ethernet network, and remote networks or computers. FVM318 VPN Overview Two common scenarios for configuring VPN tunnels are between two or more networks, and between a remote computer and a network. The FVM318 adds the option of VPN tunnels over wireless links to the FVM318.
