Normally we configure IPsec for LAN-to-LAN communication, also known as split-tunnel VPN, when only specific hosts should be reachable via a VPN tunnel. However, we may also take a different approach and configure a VPN tunnel using the full tunnel method. This means that any non-directly connected network (i.e. lan interface) will be reachable only via IPsec tunnel and not via the typical default route.

Normally we configure IPsec for LAN-to-LAN communication, also known as split-tunnel VPN, when only specific hosts or subnets should be reachable via a VPN tunnel. However, we may also take a different approach and configure a VPN tunnel using the full tunnel method. This means that any non-directly connected network (i.e. lan interface) will be reachable only via IPsec tunnel and not via the typical default route.

After setting up our IPsec instance, we will need to configure our firewall accordingly. Navigate to '''Policy & Objects → Firewall Policy → and click on a Create new button.'''. Configure everything as follows.

If you have followed all the above steps, your configuration should be finished. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly.

Using the <code><span class="highlight">'''ipsec status'''</span></code> command we can see that IPsec tunnel is successfully established on RUT router. The command output on a '''RUT''' device:

Using the <code><span class="highlight">'''ipsec status'''</span></code> or we can use <code><span class="highlight">'''ipsec statusall'''</span></code> command for a more verbose output. With these commands we can see that the IPsec tunnel is successfully established on RUT router. The command output on a '''RUT''' device:

To check if IPsec tunnel is working properly from '''Fortinet''', we can try pinging our '''RUT''' device by using this command in command line interface on Fortinet<code><span class="highlight" >'''exec ping 192.168.1.1'''</span></code>, if you are not able to ping '''RUT''' device, try changing the source interface from which we try pinging, by executing this command <code><span class="highlight" >'''exec ping-options source 192.168.5.99'''</span></code>:
