Internet connection sharing not work
You are using XP, Vista, Windows 7
You have 2 or more computers.
you have enabled ICS, and your internet connection are shared.
The LAN network card has been given the ip address of 192.168.0.1 as gateway for others.
From other computers you are not able to ping 220.127.116.11 (the google public DNS) nor able to open any page.
Here is the solution:
its highly exprienced that the antivirus or firewall program is blocking the access.
My case was Eset Nod32 Business Edition.
I open the interface, Pressed F5 wen to Firewall section, Selected “automatic Firewall + Exception” Pressed ok
i Pressed F5 again wen to Rules & zones , Clicked on second setup and on Zone Tab addred the Range of ip address of the network which was 192.168.0.1 to 192.168.101.255
and it worked very well.
if you have similar issue this may help you.
leave a comment if it worked.
