==Site to site configuration with multiple LANs==
 +
----
 +
This section provides a guide on how to configure a successful site to site IPsec vpn connection between '''RUT''' and '''Fortinet''' devices with multiple LANs. Here is the list of LANs with their subnets:
 +
* Fortinet:
 +
** LAN1: 192.168.5.0/24 with default gateway 192.168.5.99
 +
** LAN2: 192.168.4.0/24 with default gateway 192.168.4.99
 +
* RUT:
 +
** LAN1: 192.168.1.0/24 with default gateway 192.168.1.1
 +
** LAN2: 192.168.2.0/24 with default gateway 192.168.2.1
 +
===Fortinet configuration===

 +
As for the configuration of IPsec tunnel, everything is the same, only the Phase 2 Selectors, Firewall and static route sections will be configured additionally, so for other sections refer to the guide site to site.

====Static route configuration====
 +
After setting up our IPsec instance and firewall, we will need to configure our static route accordingly. Navigate to '''Network → Static routes → and click on a Create new button.''' For that we will need to create four static route interfaces, two for blackholes and two for accessing our RUT device LAN1/LAN2, configure everything the same as for site to site, just add the LAN2. It should look like this:
