Yes I can, no problem with that. Just can't get beyond it to or through the WAN. Am in London, very late here but will try again tomorrow... thanks for any help, it's much appreciated.

Thanks for your reply. I did try using a dyndns address but it got blocked as something (the router presumably) was checking the address too often so it seemed sensible to use Samsung's own service instead. I had also downloaded their dns updater to the PC so already have a reference to the public IP address. I did try the Samsung address from an unconnected machine but haven't had a chance to try the WAN IP address direct (it doesn't work from this network as I've tried it lots of times with and without the port number added!). I can't set that public address in the Samsung NetI software either. If it's all just down to being on the same network then maybe there's light at the end of the tunnel but otherwise I'm really in the dark... Sorry if my networking technical expertise is not up to scratch, I've never had to do this before - it's a steep learning curve.

I'm having trouble accessing a Samsung SHR 504X DVR conected to a Netgear cable wired router over the internet. I can connect via the local LAN IP address however. I can't get a static IP address from the cable ISP but the Samsung has a DDNS facility built in so it shouldn't be a problem... I think I've set up port forwarding correctly (does the 'service name' matter?) and have reserved the local IP of the DVR and allowed it to be a DMZ on the router. The router doesn't list the DVR as an attached device although I wouldn't be able to view it locally if it wasn't attached. Any suggestions as to what I might be doing wrong? I've been trying to sort this out for days now! Thanks.
