can not able to ping from beagle bone black to PC

[kiran nayak]

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

          UP BROADCAST MULTICAST DYNAMIC  MTU:1500  Metric:1

          RX bytes:140076 (136.7 KiB)  TX bytes:15482 (15.1 KiB)

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?

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