Wlan Clients cannot see each other

I have an 877w Dot11Radio interface with a pretty standard setup, the issue I'm having is the Wlan clients can't see/ping each other. They can all surf the net though. Do I need to allow mu to mu comms somehow?

interface Dot11Radio0

ip address 192.168.3.1 255.255.255.0

no ip redirects

no ip unreachables

no ip proxy-arp

ip nat inside

ip nat enable

ip virtual-reassembly

encryption mode ciphers tkip

ssid 10

speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0

Re: Wlan Clients cannot see each other

Hi Mathew,

On standard Autonomous AP's this is controlled via PSPF I'm not sure about the 877w but I thought it was worth a try;

Enabling and Disabling Public Secure Packet Forwarding

Public Secure Packet Forwarding (PSPF) prevents client devices associated to an access point from inadvertently sharing files or communicating with other client devices associated to the access point. It provides Internet access to client devices without providing other capabilities of a LAN. This feature is useful for public wireless networks like those installed in airports or on college campuses.

--------------------------------------------------------------------------------

Note To prevent communication between clients associated to different access points, you must set up protected ports on the switch to which your access points are connected. See the "Configuring Protected Ports" section for instructions on setting up protected ports.

--------------------------------------------------------------------------------

To enable and disable PSPF using CLI commands on your access point, you use bridge groups. You can find a detailed explanation of bridge groups and instructions for implementing them in this document:

•Cisco IOS Bridging and IBM Networking Configuration Guide, Release 12.2. Click this link to browse to the Configuring Transparent Bridging chapter: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fibm_c/bcfpart1/bcftb.htm

You can also enable and disable PSPF using the web-browser interface. The PSPF setting is on the Radio Settings pages.

PSPF is disabled by default. Beginning in privileged EXEC mode, follow these steps to enable PSPF:

Command Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

interface dot11radio { 0 | 1 }

Enter interface configuration mode for the radio interface. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

Step 3

bridge-group group port-protected

Enable PSPF.

Step 4

end

Return to privileged EXEC mode.

Step 5

copy running-config startup-config

(Optional) Save your entries in the configuration file.

Use the no form of the command to disable PSPF.

Hope this helps!

Re: Wlan Clients cannot see each other

Thank you very much for your reply. It would seem all it took was to blow away my Dot11radio 0 interface and replce a very basic config (layer 3 on the dot 0 int).

All working fine.
