It's been quite a while since I was this lost. But at least I'll learn something from it.
Ok, so I have a Zentyal 2.2/Ubuntu 10.04 machine acting as my router/server at home. It's running IPv6, I can pass the first few tests. But I'm stuck hard at enthusiast.
I've registered a domain at register4less.com (r4l). I like them, they support userfriendly.com

And they say they support glueing stuff, which I don't understand, but read about and it seems important.
Although my server at home is running a webserver, I have NO idea how to aim my r4l domain at it. I looked at the dns zones options on r4l, and got really confused. So, if someone could help me out using small words and ideas, that would be awesome.
Thanks so much!
