    "I'd like to know more about how the business WCF works"

    Then you'll want to read the related Microsoft documentation.

    "I don't see how DDNS couldn't work for OpenDNS to keep the IP updated at least."

    If your router(s) do not support OpenDNS, DNS-O-Matic or "user defined",  you can possibly flash them with alternative firmware like Tomato or DD-WRT which all can update also OpenDNS or DNS-O-Matic.

    Cool I got DNS O Matic to work... and its a shame I didn't know about this; I moved my domains to no-ip.com just to get DDNS for my TLDs which has been rather expensive than namecheap and namecheap is right there on DNS O Matic LOL 

    Now my router points to DNSOMatic it will update both OpenDNS and no-ip (although my NAS already does that as well) 

     

    now I should be able to bring up 2 other networks on DNSOMatic as well

    Oops, this sounds dangerous.  They may block your hostname due to too many abusive (unnecessary) updates then.  You shouldn't run more than one updater against a hostname.  An (one) update should only occur when the IP address actually changes.

    Good point; you're right, so its not like its updating unless the IP actually changes so yeah I should turn off DDNS on my NAS but I'd like to see if I can change the DNS alone on the NAS though so that its not being filtered by OpenDNS and I have a couple reasons for that (as crazy as it sounds) if I want to remotely download something I can't bypass something that might need to be bypassed via the NAS as its not a PC and since whatever I remotely download is visible on any PC in my house (which ARE filtered by OpenDNS) its pretty safe FWIW so I am not quite sure how to exclude my NAS from the filtering other than changing the DNS.

    "I should turn off DDNS on my NAS but I'd like to see if I can change the DNS alone on the NAS though so that its not being filtered by OpenDNS"

    The DDNS update client and the recursive DNS service being used are totally independent and unrelated.

    "I am not quite sure how to exclude my NAS from the filtering other than changing the DNS. "

    Yes, if you have the OpenDNS resolver addresses configured on the router, the only way to exempt your NAS from using OpenDNS (and its content filtering) is to configure non-OpenDNS resolver addresses on it.  I do not expect any issues.

    Thanks you've been most helpful :) 

    Yeah I found out later that DDNS & DNS are two entirely different network services and yes I see there is a way to enter a DNS manually on the NAS; so now I need to head over to the synology forum to see whether or not its for local DNS or WAN DNS as it doesn't seem to make that distinction that I know of.

    "to see whether or not its for local DNS or WAN DNS"

    Local DNS would mean your router's IP address, and this would be OpenDNS again.  You'll have to use external publicly accessible DNS server addresses, such as Google DNS (8.8.8.8 and 8.8.4.4) or Level-3 (4.2.2.1 - 4.2.2.6).  There are many more, I would think some 8000...

    I know the difference, but unlike DDRWT I have the choice of selecting local AND WAN DNS (or one or the other) I think I know what to do though.
