i have no router/no firewall
so what do i do?
Then the ISP is blocking the ports.
You can ask them to open the ports for ftp.
However, I don't think many people will come to get the DVD, they rather get it from the official linux sites.
You could try torrent, but again people download torrents from the official linux sites.
As I said before, I don't see the point for this DVD.
