    My installation is from the guide "the perfect server fedora 13 86_64" so I'm using ISPConfig 3 for all the setups.

    I'm trying to access webmail from a remote pc but consistently get:

    Unable to connect
    Firefox cannot establish a connection to the server at server1.example.com.

    I can get to webmail from the linux box without a problem (that includes logging in).
    When I do a dig FQDN from the linux box it comes back without an error.
    I did not setup the DNS with ISPConfig because I'm using Zoneedit and did not want any conflicts (did not think this is the problem).

    The only other thing I can think of is that my netgear router is blocking the port. Without putting my box in the DMZ does anyone know what port I should have open for webmail. OR does anyone have any suggestions.

    I did a web search and redid ports 143 and 993 on my router.
    Does anyone else have any suggestions?

    The "web" part of webmail should give you a hint. :p

    Port 80 and 443, both TCP.

    Hey Matty, thanks but that was it.
    I did have port 80 open (and was able to get webpages) but not 443. I opened 443 and tried to get to webmail from outside the linux box as was successful.

    Thanks a ton. I'm going to spend time learning about the various ports and services they work with.
