    Hi,

    I followed instructions in setting up the CentOS 4.3 and then installed ISP Config following the documentation on www.ispconfig.org

    I enabled HTTPS installation.

    When I'm inside my LAN environment and I use https://192.168.1.2:81 and I can successfully see my ISP Config login page.

    When I'm trying to login from outside from my office network to my home machine which is where I've installed ISPConfig on centOS, i get the following error:

    The page cannot be displayed

    But this time I accessed it with my FQDN name i.e https://www.example.com:81 and i got the above error message on my IE browser at work.

    I did not install Firewall on centOS 4.3 as I followed Falko's instructions of perfect setup of centOS . Similarly I disabled SELINUX as well at the time of installation.

    I've an ADSL modem/router, which has been configured to allow External Port: 443, 80 and 81 to internal port: 443, 80, 81 on the host: 192.168.1.2

    Also I've my dns configured with zoneedit and it works as such.

    Because when I try http://www.example.com I can see the ISP Welcome Index.html page with my FQDN name on the blue bar.

    Also when I try https://www.example.com I can see my default Apache/PHP configuration page on the centOS 4.3.

    I get the error only when I try on port 81

    *firewall at work allow to access anything at port 81

    Any information as how the ISP Config could be accessed off the internet will be very helpful.

    Thanks for your help in anticipation.

    The problem seems not to be in your ISPConfig installation, as the apache on port 81 listens on all IP addresses and domains on your server.

    Please ask your DSL internet provider if they block port 81.
