This is my situation. ISPConfig runs on Debian Etch in the perfect setup (plus desktop environment). I can reach ISPConfig on my server's static IP within my LAN, i.e. something like http://192.168.00.100:81. My sites are up and running, no problem there (http, ftp, phpMyAdmin all work), but I cannot reach ISPConf from outside, i.e. by http://www.bidevi-site.com:81. I get this message: www.bidevi-site.com refused the connection, the server may be busy etc. A little bit more about the conditions. I've got a dynamic IP address and use ddclient plus DynDNS to stay on line. The IP address for my sites in ISP Manager => ISP Site => Basis is the static IP address of my server, i.e. something like 192.168.00.100. What do I do wrong?
