Common VPN Situations

VPN Pass-through

Figure 43: 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

Figure 44: Client PC to VPN Server

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.
