I have been trying, unsuccessfully, to install an IP camera with remote access and have setup a host with DynDNS. After days of effort I tracked down my problem to the fact that I cannot connect to my router from outside. It is a BT Homehub 3 with the firewall turned off. BT will not provide any help support for Dynamic DNS despite the fact that it is configurable on this hub and their engineer has just left after checking my line and finding no faults. They assure me that they do not block anything at the exchange.
Can anyone out there suggest a fix before I jump..........?
