How can i access or make a sll vpn to a sonicwall set up with a dynamic DNS?

I have sonicwall with dynamic DNS set up... 

I also have set up ssl vpn and would like to use the sonicwall netextender to access my network.

problem is when I enter my IP or hostname from dyn.com with the port through https it is not working...

I am very new in setting up sonicwall or firewall in general so a fresher needs your help :)

Thanks
