Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

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

my server is accssible at 192.168.2.200:5222 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 92.80.109.173:5222 it times out... Needless to say, from outside my local home network 92.80.109.173:5222 is working just fine. I bet there is something trivial in the middle! But what ?

Thanks

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.
