Hi guys. I have this problem:
I need to configure ipsec vpn between 2 fortigate firewall, one in France and one to my company in Italy.
I ask for a public ip address to reserve to the fortigate, but they have a live box with only one static ip address. The live box not work with transparent mode, but the firewall is manageble
The live box have the ip address 192.168.1.1
How can i do the vpn tunnel? If i connect the fortigate to the live box and assign ip 192.168.1.2 and forward port 4500 and 500 udp in the live box for fortigate, the tunnel will be create?

Thanks for your reply!

is this over a private WAN, internet or what ?

my lan (192.168.1.0/24 10.1.1.0/24) ----> fortigate 100A <----> internet <----> fortigate 50A ----> french lan (192.168.1.0/24)

Using of live box has been easy with the help of vpn france server. It enables you to managing your records and secure your working from and dangerous threat and stop to make unknown involvement.
