If your ISP is using NAT, then either you manage to get a public IP address from them, or you change to another ISP.

Because that router is the outermost device in your network, isn't it?

yes, it is. i guess i'll have to buy a public ip.

or, if You know Your external IP, check with this site: http://www.canyouseeme.org/ whether selected port is visible "from outside".
This is better option, because probably when You can try check it from eg. computer connected to the same local network with esp8266, such a loop is generally not possible to realize through Your router.

P.S. You can try test access to esp with mobile phone too, but when mobile is connected via LTE/GPRS etc (not via Your router)

i've tried. not working because of the NAT
