Go in firefox and write
10.0.0.138
enter
Game & Application Sharing
and
Create a new game or application
WRite a name, I will call it hostingservice
check manual entry of ports
Add the necessary ports, I recommend the ports shown on the picture below.
why? Because then you got the necceary ports for
FTP server like Filezilla
Apache hosting for example a homesite for your server on xampp
Loginport and several OT servers.
Many other free ports that you can use for etc teamspeak server, ventrilo server etc.
You add the ports and then you click on apply.
Then you enter
Assign a game or application to a local network device
And assign, in my case "hostingservice" to my computer and click add.
And then your done. Pretty simple and easy.
