Problem with IP / Subdomains

[hannes171]

ok now i reinstalled the CP and named the root "mydomain.com" and forced the CP to "cp.mydomain.com", and I used my external IP adress.

But now I event cant enter the CP.

Code:

Not Found

The requested URL / was not found on this server.
Apache/2.2.9 (Debian) Server at mydomain.com Port 80

On my DNS entry at my hoster I made:

* IN A myip

so it relinks all connections to my domain to this ip.
