Dynamic VPN
Business Security Gateway can ignore IP information of clients when using
Dynamic VPN, so it is suitable for users to build VPN tunnels with Business
Security Gateway from a remote mobile host or mobile site. Remote peer is a host
or a site will be indicated in the negotiation packets, including what remote subnet
is. It must be noted that the remote peer has to initiate the tunnel establishing
process first in this application scenario.
There is one more advanced IPSec VPN application:
Site to Site – Support Full Tunnel Application
When Full Tunnel function of remote Business Security Gateway is enabled, all
data traffic from remote clients behind remote Business Security Gateway will
goes over the VPN tunnel. That is, if a user is operating at a PC that is in the
Intranet of remote Business Security Gateway, all application packets and private
data packets from the PC will be transmitted securely in the VPN tunnel to access
the resources behind local Business Security Gateway, including surfing the
Internet. As a result, every time the user surfs the web for shopping or searching
data on Internet, checking personal emails, or accessing company servers, all are
done in a secure way through local Business Security Gateway.
