Acces a web server behind two fortigate from the Internet

[Alternative]

Hi,

I would like to know how to configure a firewall to access a web server who is behind two Fortinet.

I am used to use virtual servers or to use VIP to access a server which is conencted to a Fortinet but no idea how can I do it two firewall in terms of routing.

What I remember is that NAT and NAT doesn't work.

Thanks for help

I assume you mean that you have the Web Server behind a FortiGate, who is then behind another FortiGate? All you would do is make two VIPs, one for the inside FortiGate and one for the outside FortiGate. The Internal IP for the outside FortiGate's VIP would be the External IP of the inside FortiGate's VIP.
