DynDNS on FreeNAS

[serutech]

Hi folks,
I'm trying to set up DynDNS on FreeNAS 9.1.1. and I'm getting several errors.

I've got:
Domain name
User
Password
Update URL from DynDNS

Where and how exactly do I have to put in the Update URL of DynDNS?
I've read some posts about Auxiliary parameters (--dyndns_server_name and so on) and tried that, but nothing works. There is always an error resolving the host.
Can anyone please help me?
Thanks,
Andy
