my problem solved ... a simple restart worked !
just a little query ....if a machine is connected to internet ...does it have two IP ? internal and internet ? or only internet ?
Usually of your machine is behind a router, it will have what is known as a internal ip. The router will have a public side and private side having 2 ip's on 2 very different networks. No one can cross that threshold between the outside coming in without you opening ports or having upnp enabled on your router.
There are some cases where you will get an outside ip on your computer, like connecting directly to a cable modem, connecting directly to a 3G or 4G modem (USB or PCMCIA are the common interfaces), or using dial up. These are the least secure ways of connecting to the Internet, and should have a software firewall enabled when doing so for your own protection.
It is recommended to use a router if you have dsl or cable, esp if your computer gets a Internet addressable ip.
Www.ipchicken.com will echo back your outside ip. If it is the same as your computer ip well then your computer is directly connected to the Internet.
