I have installed Ubuntu server on my pc, and I want connect via the web browser on a remote computer but I don't know how to do that.

For example, I installed MediaWiki and to login from the local computer I navigate to http://192.168.x.x/wiki, but when I try to connect from a remote computer, entering my external IP or URL doesn't display the wiki.

So what I must to do access the web resources on my local computer from a remote computer? I've already Googled this problem but I don't understand a lot. For ex. I tryed to install Apache but I don't understand how configure it.

Finally I want set the domain like

Thanks in advance (ps I'm new to Ubuntu) :)

Welcome to Ask Ubuntu! From the question I see you're having more of a networking question rather than a Ubuntu question. This is because the ability to reach a machine behind NAT (as can be seen in the example IP address you provide) really is an IPv4 thingy to configure in the device doing NAT/Firewalling/routing in your network. Unless your router is running Ubuntu, these questions are considered more ontopic on being an AskUbuntu "brother" for networking questions. – gertvdijk Jan 11 '13 at 21:47

To answer your question with few words.

You need to setup a port redirect in your CPE equipment, to forward port 80 to the IP (Internal IP) that your Ubuntu server has, 192.168.x.x.

You also need to set a DynamicDNS service, so you can be able to point to your public IP which will change over the time

Take a look at this, and google about IP address public and private and port forwarding.

Google for port-forwarding with the brand and model of your ADSL or Ca
