can not able to ping from beagle bone black to PC

Hello,
Sorry if it is too basic, but i want a urgent help, i am stuck after trying everything

I am not able to ping back from BBB to host ( host to BBB works ), using Ethernet over usb
host is windows-7 PC

That is, from BBB this wont work : ping 192.168.7.1
This works from BBB : ping www.google.com

my Debian network settings of the BBB looks like this.

eth0 Link encap:Ethernet HWaddr 88:4a:ea:de:11:cf

On the host side i have done this

manually set the ip address( 192.168.7.1), netmask(255.255.255.0) and gw(192.168.7.1) , dns( 8.8.8.8)
also shared internet from wifi to Local area network 3 which is BBB Ethernet enumeration .

Please help . Thanks

Wild idea – firewall on the Windows PC side?

Stéphane

I guess so. I have a painfull experience with MS firewall!! Take a while to learn how to unblock a certain ping!!
