Hi,
first off all. Thanks for a great product.

I wonder why in my Alias Records, your IP is listed first as hostname clap.no

INet A 90 clap.no 173.208.132.91
INet A 90 *.clap.no 92.221.224.239
INet A 90 www.clap.no 92.221.224.239

How can I change the first from 173.208.. to a dynamic IP?

You have port redirect for 81 enabled so clap.no is pointing to our port redirect server which will redirect traffic to its dynamic IP address on port 81.
