Fortigate 300D - NAT SENDING Fortigate own IP

[andersoncatao]

Hello,

I'm really new with Fortigate, and I'm facing an issue that my NAT configuration is sending Fortigate own IP on source address instead of the real public address of the request.

How can I configure Fortigate to send instead of its own IP the real address source IP ?

Thanks !

I just found the problem tht was the option "Enable NAT"

Glad you found it.

Enabling "NAT" in a policy enables source address translation. If you just check "NAT", the address of the outbound interface is used. You can define your own address (in 'IP pools') and use that instead.

This is not to be confused with destination address translation, which in FortiOS is created with VIPs. Here, you always specify the address which will be used instead of the original destination address.
