We can not see mac address of client 77.87.17.130 now.
Solution:
We use teamviewer with console access via 3g.
We can see mac address of isp(77.87.17.129) on client side.
We try to ping 77.87.17.129 but it's not working.
After 2 min ping is working.
ping starting is working after ping from client side only.
I mean from ips side we try to ping but isn't working one hour,one day.
We tried install ip 77.87.17.130 255.255.255.252 on laptop on client it's working every time.
