Hello guys!
First sorry my bad english, I'm from Brazil and I don't speak english well.
I have a public IP that I use to access my internal network, forwarding ports by NAT rules.
When I use this public IP from external network to access my website, that is hosted in one of my servers, I do this well, but when I try to access this same public IP address from my network, it fails.
DNS is not an alternative, because my port forward deppends on each port I try access.
If I use my public IP ex: 111.111.111.111:80 the Mikrotik NAT forwards to 192.168.0.1:80
If I use my public IP ex: 111.111.111.111:14253 the Mikrotik NAT forwards to 192.168.0.2:8080

I don't know what to do, because e need to access my website from my local network and it does not work, only if I try out of my local network.

Thank's so much!

Look here for explanation and solution.

And why DNS is not an option, port forwarding has nothing to do with that. You use domain names instead of IPs. Also if you use Host-based multiple-websites behind one server, you will have to use domains. Well, if hosting just one default website, that is not an issue though.
But what you are asking for is called hairpin NAT and it's easy to set by a NAT rule and eventually some small changes in the actual dst-NAT rules.
