So, I'm trying to set up a live webserver in Apache2. I've got a whole PC dedicated to hosting this one site. I've installed Apache2, I've made a start page for my website, and put some files in the right folders, I've opened up port 80 on the network, and I've pointed my domain name to the webstie on my server. I can access the website from any PC on our home network through the 192 url, but I can't access it from my domain name, or from any computer outside my network. So, basically, it seems to be working, but it's not live, What do I do?
