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 connec-
tion.
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
In this situation, the PC must run appropriate VPN client software in order to connect,
via the Internet, to VRT-401. Once connected, the client PC has the same access to
LAN resources as PCs on the local LAN (unless restricted by the network administra-
tor).
IPsec is not the only protocol which can be used in this situation, but VRT-401
supports IPsec ONLY.
Windows 2000 and Windows XP include a suitable IPsec VPN client program.
Configuration of this client program for use with VRT-401 is covered later in this
document.
