3.1.2 Remote Gateway Address Unknown Page
VPN context
Your SpeedTouch™ may have to set up (simultaneous) VPN connections with 
various remote Security Gateways. At the time you configure your SpeedTouch™, 
you have no clear idea about the location of the Remote Gateway(s) in the network. 
This may be the case in a central location of a large network, where remote 
locations may be added as time passes. It is an asset if you can configure the 
SpeedTouch™ at the central location in such a way that the addition of new remote 
sites requires no intervention at the central site. 
In this case, the SpeedTouch™ is obviously not able to take the initiative to contact 
the Remote Gateway. So, the role of initiator is excluded. Your SpeedTouch™ can 
only act as a responder for a Remote Gateway that request a VPN connection. Of 
course, both peers need to know and agree on the security parameters in order to 
have access to the VPN.A secure connection will be established with any Remote 
Gateway that meets your SpeedTouch™ VPN settings, regardless its location in the 
public network.
When this description fits best your VPN context, then the Remote Gateway 
Address Unknown
 page is your starting page for the configuration of your LAN to 
LAN scenario.
Example
As an example, this context may be encountered at the head office of a company 
that is constructing a VPN with its remote offices. New remote locations may join 
the VPN without the need of any reconfiguration actions at the head office.
