From Bravenet Wiki
The domain forwarding service will allow a user to redirect a registered domain with us, to another valid URL. After setting up forwarding it can take up to four hours for the changes to take effect.
Users should not put an encoded address into the forwarding field. If they have a URL that the user copied as “ http://www.somedomain.com/index%20one.html”, it should be entered into the forwarding box as “http://www.somedomain.com/index one.html” or else the forwarding will not work.
The domains name servers must be set to bravehost for the domain forwarding function to work.
If a user sets up forwarding to the same domain name (EX: If their domain was www.google.com and they set the domain to redirect to www.google.com), they will not be able to access there web page. Firefox normally returns a 'URL Redirection limit exceeded' error in cases like this.
