Hi, I don't know if my problem has anything to do with ispconfig but I'm really clueless by now. The problem is very weared. I have this now the second time. I worked at the ISPconfig administration and suddenly the connection is blocked. I can access every other website but no one on my server. Also the Imap connection is blocked. I restarted the server and turned of the firewall. The funny thing is, I've installed ubuntu (not working) and Vista on my Laptop. Vista can connect the Sever. It also doesn't change if I change the Internet connection (work, umts, home). I have seen this once when I explaned a customer the Administration (on his PC) -> was not nice. Is there some extra Firewall wich could block my pc? Is this possible (ip independent)? Niko
