Thread: accessing localhost subdomain from the internet

greetings!
relatively new ubuntu , linux in general... , have been playing website development on laptop @ home.
have setup server serve web project working on , accessibly via subdomain on localhost (locally, obviously).. project inside folders within /var/www/

want make subdomain accessible internet share project other people.. have made relevant router changes , base php folder /var/www/ accessible web when visit ip. however, when attempt access 1 of subdomains (i.e. http://subdomain.myip) have setup 'server not found' error in browser (firefox). see same error if attempt navigate project subfolder instead of subdomain.. i.e. http://myip/projectname.

can point me in direction of how resolve this?
i've looked in apache2 logs don't see helpful me.

subdomains setup way of adding entries 'hosts' file , have created files in 'sites-available' folder each of projects/folders/subdomains.

cheers

p.s. i'm using standard version of ubuntu, not server, if makes difference.

do have domain name pointing web server? name of domain?
