Thanks Nigel. took me a while to sort it out. I set modem to UPNP which should have sorted the problem straight away but it turned out that my firewall was being a moron. Cam will continue broadcasting throughout the night into the early hours and onward it you want to check it out then. I'll be moving it around often to try and catch the variety of feeders and birds as much as I can. I've had what appears to be an ex racing pigeon (it has both legs ringed) visit my garden every day for about a week or so now and I finally managed to get it feeding from my hand today. I call it Jeff although I have no idea if it's male or female. He's lovely though, haha.
uPNP is a great idea, but unfortunately it doesn't always work well, especially with the routers supplied by ISPs, as these tend to be loaded with special firmware, to limit them in various ways.
I've set-up lots of this sort of thing over the years and they can be a pain to get everything just right, I've always used Comodo firewall products where possible as they are one of the few that actually provide the proper controls for port control. though of course it can be a bit daunting, if you are coming to it from something simple like Windows firewall
By the way ...
