Unable to get internet on Hyper-V VM

Hi,

I am running one VM on my Hyper-v Server.

The physical machine has 2 network adapters and i have created two Virtual switches using those adapter - Internal and External.

Internal is connected with my LAN and is working fine and the domain name is showing.

External is connected directly with the ISP and it has static public IP. I am not getting internet using this line.

However if i am providing the static IP to the physical server in which the hyper-v is running, it works fine. But when i use the same with VM it does not work.

Am really confused please help.

Thanks Chandan
