There is currently not a dyndns feature integrated in the image.

i configured a dyndns account at dyn.com/dns/
No panic, its for free IF you chose to test the PRO account. Then cancel the PRO Trial immediately and you can keep 1 dns host for free.
Forward the port at your router and access the WebIF portal via dyndns from the Internet...

i don't understand your question:
a non - ip or dyndns account has nothing to do with the Box itself.
It is just a way to enter your home network from the internet due to a 24h changing ip address of your internet provider.
- get an dyndns account / host
- enter this dyndns host at your router
- forward the specified port (for webif = 80) in your router for your box IP
--> enter webif of your box from all over the world

i use dyndns service an the webif to configure timers from work. There is no need of plugins at the gigablue...(okay, the webif plugin )

But if he hasn't a router with dyndns feature? This is his question.
What ever ... there is not a dyndns client in the box integrated.

Well, then also it has nothing to so with the Box. He has to Check if his Router has this Feature...

But you can add the dyndns Host at the config file of cccam? Its Not that comfortable but it Works

Yes sure ... this is possible.
