access to the webserver behind the mikrotik

hello everyone
actually i have a mikrotik router and configure as a hotspot server , i plugged it to the modem and with ppoe client via mikrotik connecting to the internet.we have a valid ip that setting on when ppoe connected .
we have a web server behind the mikrotik and installing a web based software on it with ip 192.168.15.14 ,there is a website on internet that in the main page of it have a hyperlink to our web server such as this x.x.x.x/hotel when you click on it.
the question is customers from outside cannot open our web server via browsers after installing mikrotik, i set a dst-nat rule like valid ip in general tab goto 15.14 in action tab and the counter goes up but nothing happen ???
anyone have an idea ???

Firewall filter rule?

no nat rule

I mean did you create a rule in your filter rules. Nat is needed, but probably filter rule is also needed.

it solves dude , the problem was server doesn’t access to the internet
