IPSec VPN between two networks
In the following example users on the main
office internal network can connect to the
branch office internal network and vice versa.
Communication between the two networks
takes place in an encrypted VPN tunnel that
connects the two DFL-200 Network Security
Firewalls 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 the example, you can use the
DFL-200 to protect a branch office and a small
main office. Both of these DFL-200s can be
configured as IPSec VPN gateways to create
the VPN that connects the branch office
network to the main office network.
The example shows a VPN between two
internal networks, but you can also create VPN
tunnels between an internal network behind
one VPN gateway and a DMZ network behind
another or between two DMZ networks. The
networks at the ends of the VPN tunnel are selected when you configure the VPN policy.
Creating a LAN-to-LAN VPN Tunnel
Follow these steps to add a LAN-to-LAN Tunnel.
Step 1. Go to Firewall and VPN and choose Add new.
Step 2. Enter a Name for the new tunnel in the name field. The name can contain
numbers (0-9) and upper and lower case letters (A-Z, a-z), and the special characters -
and _. No other special characters and spaces are allowed.
Step 3. Specify your local network, or your side of the tunnel, for example
192.168.1.0/255.255.255.0, in the Local Net field.
Step 4. Choose authentication type, either PSK (Pre-shared Key) or Certificate-based. If
you choose PSK, make sure both firewalls use exactly the same PSK.
Step 5. For Tunnel Type, choose LAN-to-LAN tunnel and specify the network behind the
other DFL-200 as Remote Net. Also specify the external IP of the other DFL-200, either an
IP or a DNS name.
Click the Apply button below to apply the changes or click Cancel to discard changes.
Repeat these steps with the firewall on the other site.
