Appendix C - About VPNs 

 

123 

 

 

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. 

 

In this situation, the PC must run appropriate VPN client software in order to connect, 
via the Internet, to the Wireless ADSL2/2+ Modem Router 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 

ADSL2/2+ Modem Router supports IPsec ONLY. 

•  Windows 2000 and Windows XP include an IPsec VPN client program. However, 

configuration of this client program for use with the Wireless ADSL2/2+ Modem 
Router is very complex and beyond the scope of this document.
