DNS Records - Website redirection without direct ip

I have registered a domain on godaddy.com. I want to achieve the following:

• Redirect to other domain on Minecraft port 25565: solved by adding a SRV record
• Redirect to other domain on Teamspeak port: solved by adding a SRV record
• Redirect to website (format userxyz.myhoster.net - redirecting to IP not possible, only via this URL): not solved. CNAME record doesn't work.

Do you have any idea how to solve this problem? Thanks in advance.
