Fortigate Site to Site VPN

I would like to add some more simple configuration, this time VPN Site to Site between a Fortigate and a CheckPoint firewalls,

For an ease of access I'll split this to two parts, so let's start with the easier, the Forti :

So, first thing – create an address object for the LAN of the NGX

With that out of the way create Phase 1, I used DES for encryption and MD5 for authentication, feel free to change it as you wish, I matched the keylife to Checkpoint's default settings

Now, phase 2 make sure to specify the source and destination for the tunnel – may cause problems if it's set to any.

And last thing to do is a rule to allow the actual tunnel,

 from internal to external action "ipsec" and choose the tunnel.

And that's it for the fortigate's side.

P.S.
This configurations apply to Version 3 and above.
