Is there any quick answer that lapses me by to this situation -

my server is accssible at without a problem (from within the local network of course) but if I try to reach it from within the local network through the ISP provided public IP address it times out... Needless to say, from outside my local home network is working just fine. I bet there is something trivial in the middle! But what ?

What type of firewall/router do you have? You need to make it support hairpin' NAT. This is simply impossible on some equipment. – Zoredache Feb 27 '12 at 19:57
It is an Edimax something. Nothing fancy, and it's the first time I hear this 'hairpin' word together with NAT. I'll google on it. – kellogs Feb 27 '12 at 20:27
Click the link that I provided, there are many similar questions here. I suspect you are out of luck though, given what I see on the Edimax pages. It appears to have a relatively limited level of functionality. – Zoredache Feb 27 '12 at 20:58
maybe so, anyway the answer is correct, so you could turn it into an proper answer – kellogs Feb 27 '12 at 21:19

You need to setup port forwarding on your router and forward that port number to your internal IP.
