New here to Apache Friends forums, sorry I don't speak German, just English.
Anyways to the problem. I recently decided to start to learn Linux (Ubuntu more specifically) as I have never used it before and have always heard its fun to use and great for servers. Which is exactly what I'm -trying- to use it for. I have a dedicated game server running just fine, even XAMPP is running fine. I can access my website via http://localhost http://192.168.1.12 (internal ip), my external IP, and my DynDNS. All on my internal network. But everyone outside my network cannot access it. I have port 80 forwarded on my router, I've even gone DMZ, my ISP has told me (was also confirmed by the technicians supervisor) that they do not block port 80, and I have no firewalls running on the server its self. I cannot seem to figure this issue out. I was having the same problem while running Windows Server 2008 as well, could not find a resolution. Does anyone have any idea as to what's going on with this? canyouseeme.org is giving me 'Connection Refused' on this (Windows) box and 'Connection timed out' on my Linux (server) box.
Oh and also in my httpd.conf, I've got "Listen" set to Listen 192.168.1.12:80 at the moment. I've tried several variations such as externalip:80 and dyndns:80 and just 80 by its self. Same with ServerName. Currently set to externalip:80. Have tried internalip:80, dyndns:80, externalip:80, nothing works.
Any comments or help is greatly appreciated.
Edit: sorry was long day, didnt see the English forums.
