I have an 871W router with a couple of clients connected. If 2 devices are both connected to the router the devices cannot ping each other. I can ping both devices from the router but not from the device. If I connect 1 of the devices to the ethernet switch of the router than I am able to ping the device from the other device. Any ideas why I cannot ping the device from the other device when both are wireless?
Solved! Go to Solution.
Your config changes got it working. Thanks for your help. Would you mind explaining why I needed these commands to enable this type of access?
As you see the radio interface works bridged to BVI interface. But being an AP, it is a special kind of bridge.
The commands (no source-learning) allows that a packet received on the radio interface is also sent to all the other connected wireless devices.
Thanks for the nice rating and good luck!
It might be your ACL, try this.
access-list 100 permit icmp any any echo
The echo requests may be getting blocked.
But it doesn't appear the ACL is blocking any traffic, and cisco's ACLs are supposed to behave in a predictable way.
