TODO:
Have you had issues with computers not being able to see or ping each other on your LAN?
Example: Computer 1 cannot ping Computer 2, but Computer 2 can ping Computer 1.
SOLUTION:
Open Cisco VPN Client. Got to Options. Uncheck the Stateful Firewall check box.
You should now be able to ping in both directions.
NOTES:
This post only applies if you are running Cisco VPN Client.
