So I've set up a LAMP web server on Ubuntu 14.04 server distro and installed owncloud as well as wordpress on it. It's connected to the web via ethernet and connectivity is good as far as I can tell (it can ping sites and pull in updates just fine). While I am connected to the wireless network from the router to which the server is connected (same network), I can access wordpress and owncloud just fine. However, the problem comes when I try to access it from a different network location (like from back at my apartment). The session just times out.
I checked the port forwarding (ZyXEL PK5001Z-CenturyLink router) for both port 80 and 443 as instructed by http://portforward.com/english/routers/port_forwarding/ZyXEL/PK5001Z-CenturyLink/Apache.htm. I've tried pinging each of those ports at the server's IP address with no luck.
I'm pretty new to programming and networking, so this is probably an easy fix, I just don't know where to look. Any suggestions would be greatly appreciated. The information for the server and addresses is listed below. Thank you in advance.
URL: fernweh.ddns.net "/wordpress" or "/owncloud"
dynamic ip assigned through noip.com
Okay, so I configured noip2 as suggested and still no luck. I also set up port forwarding on a couple higher ports (as suggested as well), still nothing.
I then checked to see what ports were actually open using
'nmap -v -sT local'
Which found 1000 ports, only 2 of which were not filtered
'80/tcp http open 443/tcp https closed'
Do I need to open up more ports using
'iptables -A INPUT -p tcp --dport "port number" -j INPUT'
Or is this irrelevant?
