Reference Manual for the ProSafe VPN Firewall FVS318v3 VPN Process Overview Even though IPSec is standards-based, each vendor has its own set of terms and procedures for implementing the standard. Because of these differences, it may be a good idea to review some of the terms and the generic processes for connecting two gateways before diving into to the specifics. Network Interfaces and Addresses The VPN gateway is aptly named because it functions as a "gatekeeper" for each of the computers connected on the Local Area Network behind it. In most cases, each gateway will have a public facing address (WAN side) and a private facing address (LAN side). These addresses are referred to as the network interface in documentation regarding the construction of VPN communication. Interface Addressing This example uses addresses provided the VPN Consortium. However, when you set up your own equipment, you will be using addresses specific to the devices that you are attempting to connect via IPSec VPN. 10.5.6.0/24 LAN IP 10.5.6.1 VPN Consortium Example Network Interface Addressing 172.23.9.0/24 Gateway A 14.15.16.17 WAN IP 22.23.24.25 WAN IP Gateway B LAN IP 172.23.9.1 Figure C-4: VPN Consortium example network interface addressing Make sure the addresses do not overlap or conflict. That is, each set of addresses should be separate and distinct. Virtual Private Networking C-7 January 2005
