I'm working on a fairly new Cisco wireless install and we just discovered that (any) two wireless clients cannot find/ping/connect to each other when they are both on wireless.
I'm working on a TAC case for this now, but I wanted to see if anyone has run into this. Here are some details of our setup. Flex 7510 controller running 7.3.101.0 APs are 1042 (most testing done here), 2602, 3502. APs are all in FlexConnect mode. Wireshark shows the clients arping and never getting a response to the ARP so it never finds the other client. Even with both clients on the same SSID/VLAN/AP. All connectivity to the wired network works fine. We have not yet verified how far the ARP gets on the network, but it seems to be a problem at the AP since two clients on the same AP can't ping each other. If one client goes wired, they can ping each other. We have broadcast forwarding enabled on the controller and P2P blocking action is disabled. Thanks for any thougts you may have.
