6.11 VPN (IPSec) Example
Common VPN Situations - VPN Pass-through
Figure: 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 PC to VPN Gateway
Figure: Client PC to VPN Gateway
In this situation, the PC must run appropriate VPN client software in order to connect, via the Internet, to the
WN-300ARM-VPN or other VPN Gateway. Once connected, the client PC has the same access to LAN
resources as PCs on the local LAN (unless restricted by the network administrator).
 IPsec is not the only protocol which can be used in this situation, but the Wireless ADSL Router
supports IPsec ONLY.
