6.1 Common VPN Situations
VPN Pass-through
Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the Router/Gateway is NOT
acting as a VPN endpoint. It is only allowing the VPN connection.
• The PC software can use any VPN protocol supported by the remote VPN.
• The remote VPN Server must support client PCs which are behind a NAT router, and so have an IP
address which is not valid on the Internet.
• The Router/Gateway requires no VPN configuration, since it is not acting as a VPN endpoint
Client-to-Office VPN Gateway
In this situation, the PC must run appropriate VPN client software in order to connect, via the Internet, to the
IP-2000VPN. Once connected, the client PC has the same access to LAN resources as PCs on the local LAN
(unless restricted by the network administrator).
• Windows 2000 and Windows XP include a suitable IPSec VPN client program. Configuration of this
client program for use with the IP-2000VPN is covered later in this document.
