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.
