What you are telling Admin Tools to do:

When someone visits http://www.dev.origin-gi.com/en redirect them to http://www.dev.origin-gi.com/en/component/content/featured.html

If you are trying to really do that, it won't work. The /en is a special URL created by multilingual sites and is handled by Joomla! itself. You can't redirect it. If you could do that you'd end up with an infinite redirection loop.

What you probably meant to do:

When someone visits http://www.dev.origin-gi.com/en/component/content/featured.html redirect them to http://www.dev.origin-gi.com/en

I believe this can be done with
Existing URL: http://www.dev.origin-gi.com/en
New URL: en/component/content/featured.html

I have to tell you that since the /en prefix is special for Joomla! (it is internally transformed to lang=en and removed from the URL) it is STILL possible that the redirection will fail. I'm afraid that the "multilanguage" feature of Joomla! is a minefield of arbitrary decisions and lack of fundamental logic. Take this from someone who has aided in the triage and fixing of known issues with it...
