Hi, I have a Q-See QSD6209 nine-channel DVR (please don't laugh, I'm new to this, I see what people think about these!). I don't think this is the usual port forwarding problem.
I have the DVR installed at my store, using port 80 with port forwarding via my Comcast Business Gateway. I'm using DynDns. I've verified that it's possible to connect remotely to my DVR. But I can't connect to it from home, because my Netgear WGT624 wireless router seems to be causing the connection to fail. It doesn't matter if I'm using the wireless interface or hardwired cable to the router.
If I plug my computer directly into my Comcast cable modem, I can connect OK. Why would going through the router block the connection? It has a built-in firewall which doesn't appear disable-able, so would this be the culprit? I temporarily turned on port-forwarding for incoming connections on port 80 to go to my PC, but that didn't help.
Thanks for any help.
