I followed the tut on the site to get a Ubuntu server running everything went smooth and I can access the server via external IP address. I have two problems now, I want to know how to connect the external IP to a domain name (I have one in namecheap already) and also when i try to connect to ISPConfig via :8080 using external IP it does not come up but it loads perfectly fine locally (ubuntu.lan:8080)
Is the DNS at NameCheap pointing to your outside IP address? Does your router forward the needed ports from your outside IP address to your local one? (ports 80, 8080, 53, 25, 110, 443, etc.)
Port 8080 not just open but forwarded from the router to the local server IP. Since the website comes up it would appear port 80 is forwarded. No idea other than that. Sorry.
