- Wed Dec 02, 2015 4:42 am #35485 yes, i specified it in my sketch.
i don't think i need DMZ because it works fine in my LAN, so when i write 192.168.1.150:802 (150 for example) it works.

Anyway i find out my ISP using NAT and i think that's why it's not working on the WAN.
Does anyone know a way to make it work with NAT? without changing ISP?

- Wed Dec 02, 2015 5:05 am #35487 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?

- Wed Dec 02, 2015 5:25 am #35491 Open a browser on a device connected to your router and go to http://www.whatsmyip.org/ and then use the browser to go to the listedIPaddress with the port - <listedIPaddress>:802 and see if that works.

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)
