If I understand correctly, you installed OpenGoo on some PC and want to be able to access it from that same PC and from outside of the PC (either by a domain name or by its IP address), right?
Then, you should be able to access OpenGoo locally as well as externally by using that same domain name or IP address. Just be sure that the value for ROOT_URL in config/config.php is the domain name or IP address.
If you still want to use '
http://localhost' for some reason when accessing it locally you could set the ROOT_URL value to the path after 'localhost'. Example, if you installed opengoo on '
http://localhost/opengoo' then you would set the ROOT_URL to '/opengoo'. This would allow you to access it through any domain name or IP address. But, when URL's are generated in OpenGoo, they'll start with '/opengoo' instead of '
http://something/opengoo'. This is specially annoying when you receive notification emails that contain URLs from OpenGoo, because your email client won't recognize '/opengoo' as an URL and so you can't just click it to access OpenGoo (and even if you could click it, without the '
http://server' part it wouldn't take you anywhere).
Cheers.
