I can't access /var/www/web7 either. I looked on my server and in /var/www/ there is a folder for www.mydomain.com
but its a shortcut to /var/www/web7/ so I think the thing you were talking about linking is already done. (web7 is the username that ISPConfig assigned the specific site)
It has to be something on my server computer blocking access but I can't tell what. Could it be something to do with the fact that i am trying to access it in the same local network? Maybe since I'm typing in the public static IP address its messing up? I checked the firewall and the port forwarding for port 21 and both appear to be in order. I'm really at a loss to what the problem is, because these appear to be all the right settings, it just doesn't work.
