Port forward from local network

RouterOS General
1

Hello,

I setted up MikroTik routerboard. It works perfectly but I have a small problem.

Internet — Routerboard(10.37.10.1) — Server(10.37.10.251), MyPC

I forwarded port by this code:

[admin@MikroTik] /ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic 
0   chain=srcnat action=masquerade src-address=10.37.10.0/24 
     out-interface=ether1: WAN - public 

 1   chain=dstnat action=dst-nat to-addresses=10.37.10.251 to-ports=80 
     protocol=tcp dst-address=externalIP dst-port=80

It works perfecly, but only from internet. When I want from MyPC connect to externalIP:80, I will get timeout. Is there any way to make this working?
