Problem with e-mail server

Hello,

 

I have a problem when the mail server is connected through the FortiGate 60E.

FortiGate local IP is detected instead of client local IP each time when a user is trying to connect to his email address and this thing is causing server blocking FortiGate local IP , in case of a Brute Force attack, instead of blocking individual client IP.

Is there a way to forward client IP to the email server ?

 

Thank you

Kind regards.

Turn off NAT on the inbound policy (VIP to mail server)

Good catch Bromont! I agree; make sure the NAT green button is turned off.

Turning NAT OFF, will cause mail server be inaccessible. Any others ideas ?

Thanks

Does your mail server have the FGT as it's default gateway? Are you able to provide a simple network diagram of your setup?
