When you say type in url from a neighbours computer what exactly are you typing? what means have you set up so that your LAN responds to http requests, only ask as you state your not a super tech but you do have basic network knowledge? You have a fixed IP ? Your firewall,router passes port 80 requests through to your server? You arae aware that ‘localhost’ is a loopback address it can only ever be seen from the machine you’re working on and refers to that machine, localhost never broadcasts as it were to a WAN and can’t be seen from outside.
