In spite of giving much effort in making successful ping between a real windows7 pc and virtual router in GNS3 Topology,I became unsuccessful to do it.
1.windows firewall disabled.NO antivirus running.
2.microsoft loopback adapter added (ip-192.168.1.10/24,gw-192.168.1.1)
3.router added in gns3 and configured (ip in interface fa0/0-192.168.1.1/24,no shut given)
4.cloud added and its loopback added to router fa0/0 interface
It is tried for window7 and xp machine.
Kindly help me resolve the problem.
