Error while using NAT'ed IP

While I do not have any experience using Joomdle through a NAT at this time. Technically, there should be a way as long as its all transparent to Joomdle, Joomla, Moodle (really any application). Depending on the device(s) you have setup in your network you may need to set up some form of translation, direction or even tunneling. Without know how you are using your NAT its a little difficult to comment.

For example for certain games you will need to configure your NAT to route particular protocols and/or ports. Similarly, something may need to happen.

I would set up and test the environment entirely without a NAT a first to ensure all is working. And then insert the NAT into the equation. If you suddenly run into problems, at least you know that you will need to configure your NAT and/or applications.

We have seen similar situations before with Joomdle installations but more widely with any applications that are trying to connect using furl_open, a php command. Many firewalls prohibit this command by default but can be configured to allow it. See this discussion, while the firewall is Sonic, it is still a firewall.

You can see the solution down near the bottom by changing one of the firewall settings.

Note this is different than allowing ports to a particular IP address. Instead this is about the PHP Headers where this command is using HTTP 1.0.

You can do a search for furl_open, php, your firewall php get contents for more details.

Also, if you would like you can try using R0.25 which supports both furl_open and CURL which is another protocol for getting remote data between applications. To update to R0.25 would require a complete re-installation of Joomdle. Joomdle in Joomla and Moodle.

Let me know if you would like the R0.25 file and I can send it through email.
