I changed my domain registar. The nameservers attached to my domain are now set to the registar’s. However, if I change the nameservers back to my box’s, the registar’s website shows an error that the nameservers are not responding.
So I decided to setup external DNS (at least for now), but when I go to my VPS’ ip I get redirected to the domain, which of course doesn’t work.
So I wonder how to set up a box if a registar doesn’t allow non-responding nameservers to be set.
I found the problem now… I didn’t set the glue records, because my registar’s interface doesn’t allow it (I thought I was setting glue records). I asked them to set the glue records manually, they did. Then I could set the nameservers. Very weird registar for not supporting glue records, but I am glad the issue is resolved!
