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 '''spoke (RUT)''' device:

To check if IPsec tunnel is working properly from hub (Fortinet), we can try pinging our spoke (RUT) 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 spoke (RUT), 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>:
