Is airtel blocking anyport for dynamic IP's?

Hi,

I am having a problem in port forwarding from my home belkin router 9000 port to my home PC 9000 port.

I have configured virtual servers in my belkin router but,

I am not able to access any port of my pc from outside. but if i give access global ip address(dynamic) in browser i am getting connection reset by peer error.

is airtel blocking any direct connection.? I am using dynamic IP.
