Configuring SILBO Router/gateway:
Login to router using default IP 192.168.10.1 and default credentials admin/admin.
Once login we can see the FW version.
Change the IP address to required IP, in this testing we are using 192.168.11.1 IP address.
To do that Navigate to Settings>>Network from 192.168.10.1 to 192.168.11.1 and save / update.
Upon IP changed configure VPN.
Navigate to >> Settings>>VPN>> IPsec>> and do as per below images
Once all the configuration is correctly configured and clicked on save button device will show VPN configuration >> General settings.
Save and then navigate to VPN>>Ipsec setting page and click on update.
In some time IPsec will come up and it can be seen as established as shown below.
Also in FortiGate it can be seen as below.
To Ping server LAN, navigate to features>>Others and give LAN IP and ping.
If the ping is not working then check the firewall side settings whether the ping is allowed or not.
