question about remote connect

Hi,I have nanostation,and try to connect remote over internet but I cant.Nanostation IP is 192.168.88.90 and lan ip address on mikrotik router is 192.168.88.1/24
On nanostation I set open http port 8080,and I have dyndns address www.someone.dyndns.org, I try to put this local adress in nat firewall but no success.
I try with someone.dyndns.org:8080, but no success.Can somebody explain me how to set that I can remote connect on my nanostation over inernet.
I set dyndns script on my mikrotik and work fine.

thanks
