Server Blocked?

[Reflux]

I set up an FTP and Apache web server on my home comptuer. I port triggered all the correct ports: 21, 20, and 80 I even tested it form another computer outside the network but when i try and log in from school the website does not work and neither does the ftp server. I can understand why the ftp server wouldnt work but could they have blocked my site just because it is hosted form a residential isp?

Do you actually mean port triggering?

What, specifically, doesn't work? Does DNS (if used) fail to resolve? Is the connection to your server timing out, or is it being refused? Fire up a sniffer if you're not sure.

Also, does your school enforce the use of a proxy to reach the outside world?

a trace route may also reveal where some thing is falling apart.

If you're running Windows XP SP2, chances are, your ports are blocked by their firewall by default. Go to Windows Security Center or Control Panel -> Windows Firewall to disable it. Also some cable companies will automatically block port 80. Most, if not all cable companies prohibits home servers.

Have you tried using a static LAN IP and port forwarding instead? Or using apache on port 8080? I run a few things on ports above 50000 myself so this might work.
