How to access a public static IP address from the LAN?

Hi all!

First of all, sorry if I don’t explain myself correctly or if I not express myself in the right words, English is not my mother language.

I have a router (OS ver. 2.9.46) which I need to configure.
The router has 2 WAN interfaces (one pppoe regular ADSL service and the other is a dedicated synchronous connection) and 1 LAN interface.
The dedicated connection has 5 static IP addresses.

I have defined the five static IP addresses and the routes associated to both WAN interfaces.
I have two NAT rules to masquerade the WAN interfaces and defined a third rule to make a NAT translation to a internal server which runs a web server instance that I want to expose to Internet, associated to one of the static IP addresses.
The NAT rule is working perfectly, but when I try to access that static IP address from within the LAN, the only response I got is from MikroTik router os administration webpage.

Is there any way to make that when I access that static IP the router send me to the address as if I were accessing it from the outside?

Thank you all in advance and sorry if I’m not begin clear enough.

1st change ports of RouterOS services.
2nd make a drawing.

The simple way to achieve this would be to create a NAT rule that forwards port 80 requests to the LAN IP address you have the webserver on.

Public IP Port 80 Request > LAN IP Address Of Webserver

Check this WiKi Article for help with the NAT rule,

Hope this helps
