well i m setting up my ddns
but what i see is i can get my site when i enter the domain from wan side
but lan side it can't be found
so when i call my domain on my local computer it can't get the site
but when i call it from my phone which is not on my local network it works...
am i missing something ?

What you are experiencing is normal. When inside the same network, you need to access the website using its internal IP address because routers do not allow bounce back traffic.
