Help with postgis access from internet

Hi!

Recently i’ve manage to install Truenas Scale for my office. In it i have deploy postigs as a custom app and is working ok.

I have no problem to access postgis (using pgadmin) from my office LAN but the issue is i cannot access it from internet.

I am currently using DynuDNS and a custom domain to acces different apps in my office servers (i have two) over internet. The port i want to use is open in the office router and it checks open when using yougetsignal port forward checker.

Y have also configured Truenas Scale Sysctl commands for IPv4 and IPv6 forward.

thanks in advance!
