Autokey IPSec VPN between two networks
Use the following procedures to configure a VPN that provides a direct communication link between users
and computers on two different networks.
Example VPN between two internal networks shows an example
VPN between the main office and a branch office of a company. Users on the main office internal network can
connect to the branch office internal network and users on the branch office internal network can connect to
the main office internal network. Users on the branch office network can also connect to services such as an
email server running on the main office network.
Communication between the two networks takes place in an encrypted VPN tunnel that connects the two
DFL-500 IPSec VPN gateways across the Internet. Users on the internal networks are not aware that when
they connect to a computer on the other network that the connection runs across the Internet.
As shown in
Example VPN between two internal networks , the DFL-500 is designed to connect a
telecommuter or small branch office network to the Internet. You can use DFL-500 IPSec virtual private
networking to connect the branch office network to a main office network protected by a DFL-500 product that
supports more users, such as the DFL-500-300.
You can also use the DFL-500 to connect to a network protected by a third-party VPN gateway that supports
IPSec and Autokey IKE.
Use the following procedures to configure an IPSec Autokey IKE VPN between two internal networks:
·
Creating the VPN tunnel
· Adding source and destination addresses
·
Adding an IPSec VPN policy
