You must tell your router that it must forward any HTML request to your HTTP
server PC.
Something like
create protocol=TCP inside address=10.0.0.190:80 outside
address=62.251.10.121:80
where you must replace 10.0.0.190 with the LAN IP address of your server PC and
62.251.10.121 with the IP address you obtained from your ISP.
Study the manual of your router for details.

From a PC outside your LAN your server is accessed by
http://IP-address-you-obtained-from-your-ISP
(the browser assumes that there is a file index.html)
You can only use a name if it is registered to correspond with the IP address
you obtained from your ISP.

It is a good idea to give your PCs a static IP address instead of leaving that
to the DHCP server, because if it allocates a different IP address, things don't
not work anymore.
