Im trying to access my cctv cameras pvr (not ip cameras) over internet from a dyndns account - xxxxxxxxx.dyndns-remote.com

its fine when on my own wireless network 192.168.1.90

But Im just not sure why
1. IP address is not updating automatically on dyndns account using cctv to do it?

does anyone know what to type into my router ddns to do this instead to get ip address to update (DDNS) Wont let me continue without entering a Domain?

DYNDNS.ORG
Host: xxxxxxxx.dyndns-remote.com
Domain:
Username: i know
Password: i know

Why are you configuring the dyndns on the router and the cctv box? Also no need to configure that to test the port forwarding, as you can just use your dynamic ip address from home.

It is possible that by setting up the dyndns in the router you are automatically opening up its Web interface to the internet, and as you have port 80 running for router AND CCTV on the single IP address the router probably wins.

So

1. Enable 80 external to port 80 internal
2. Enable port 9000 to port 9000 internal
3. Try this over internet using just the external IP address
4. Once that is working
5. Try setting up the dyndns in the CCTV box, after turning it off on the router

If your HG523 is anything like my HG533, and the user interface is pretty much the same, you should be entering xxxxxxxx as the host and dyndns-remote.com as the domain. That should get your DynDNS update working properly at least.

As far as port forwarding goes, I think you should probably remove the "remote host" field entirely and leave it blank. With the local IP you have in there at present, I think it will cause problems. The "remote host" field is there to only allow access via a specific remote IP address (e.g. the IP address of your computer at work), in case you do not want open it up to the world - you shouldn't be putting the router IP address in their (of course, the router knows its own IP address).

your DNS setting in the PVR is wrong, says 192.162.1.1 or something similar. This could be causing the dyndns not to update.

Also, as futura says the remote host should be "all" hosts so either blank or maybe 0.0.0.0 depending on the firmware
