New to TrueNAS - Apache Directory listing

[dudumomo]

Hello,
I'm a modest mirror admin and I wish to migrate to TrueNAS, yet I got couples of points I am not able to do, as being new to TrueNAS.

I have a simple requirement that is to list the directories through Apache, that I have mirrored.

To do so, I've created a custom App with Apache (HTTPD) inside and set it on a specific IP and with specific datasets.
I can browse the IP and it shows IT WORKS

But I have no clue how to remove it but also how should I redirect my domain name to this local IP as I guess I need to set it up in TrueNas as well

Thank you for your help
