I'm so close to getting this working. I've set up the zone file as I think I should.
A record is tunnelhost.intro-triangle.com
NS record for tunnel points to tunnelhost.intro-triangle.com
However when I run the testing page it says it's not delegated
http://code.kryo.se/iodine/check-it/ is the test page and I'm entering tunnel.intro-triangle.com even if I'm running iondined on the server.
Does it look like it's configured correctly?
