DynDNS and Draytek 2820n

[elrasho]

I'm using this guide to setup DynDNS on my router: http://www.overclock.net/t/305677/how-to-remote-desktop-and-routers-dyndns

When I RDP to my hostname and enter the DynDND or PC login details it says they are wrong, am I missing something??

I've entered the DynDNS details in my router

EDIT: nvm it works I was being a noob
