Access mail server from internal lan

[Canapla]

Hi everybody

I'm quite new so sorry if it's a dumb question

At work I have a FortiGate 40F and a mail server on a Synology NAS, I have open the ports that I need to connect the server from internet and added all the roules. Now I can connect to it from home with PC and Phone using a FQDN.

The problem is that when I go at work and the Phone connect to the WiFi (internal lan) the mail app on the phone stop to work using the FQDN but I must use the internal IP.

Must I add a new Rule? Where?

Sry again for the dumb questio

Thanks Stefano

Hello,

You are doing VIP to translate from public to private IP right? If this is the case then from local LAN, you will need to configure hairpin NAT to be able to use same fqdn/public-ip.
