Using a 871W, the clients on the wireless segment cannot connect to
each other (same subnet). Here is the relevant part of the config:

-----------------------
!
interface Dot11Radio0
no ip address
!
encryption key 1 size 40bit 7 XXXXXXXXX transmit-key
encryption mode wep mandatory
!
ssid myssid
authentication open
!
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0
36.0 48.0 54.0
station-role root
no dot11 extension aironet
l2-filter bridge-group-acl
no cdp enable
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
!
interface Vlan1
description $ETH-SW-LAUNCH$$INTF-INFO-HWIC 4ESW$$FW_INSIDE$
no ip address
ip tcp adjust-mss 1452
bridge-group 1
!
interface BVI1
description $ES_LAN$$FW_INSIDE$
ip address 192.168.0.3 255.255.255.0
ip nat inside
ip virtual-reassembly
ip tcp adjust-mss 1452
!
!
control-plane
!
bridge 1 protocol ieee
bridge 1 route ip

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

Any thoughts?

Thanks

I dont see it in your config, but it sounds like you may have Public Secure
Packet Forwarding enabled.

1. Can EACH of the wireless workstation in question ping the BVI IP
address 192.168.0.3 ???

2. What does arp -a ( command windows) show on a given wirless
workstation when you ping one of the other wireless workstations ?

Yes, each can get to their gateway of 192.168.0.03

>2. What does arp -a ( command windows) show on a given wirless

Tried this - they do not have each other's MAC in their arp cache.
Just that of 192.168.0.3

>bridge-group x port-protected

Nope - that is not in the config

Further ideas?

Thanks

Do you have a firewall enabled on these clients ?

If so disable it
