Can't ping WLAN clients from other WLAN clients



  • hardware:  Mini ITX board with onboard intel NICS
    PFSense V. 2.0.1-RELEASE (i386)
    interfaces:  WAN:    em1
                    LAN:    em0
                    WLAN:  ath0

    setup:
    I have two subnets, one for LAN and one for WLAN and they are:
    LAN:  172.25.47.x/24
    WLAN: 172.25.48.x/24

    both have DHCP pools, both have 'any,any' rules setup for each interface under 'Firewall –> Rules'
    I have bridged the LAN & WLAN under 'interfaces --> bridges'

    Problem: 
    I would like for the WLAN clients to be able to access the LAN clients and the LAN clients to access the WLAN clients.  Also I want the WLAN clients to access the other WLAN clients.  If I can using a LAN client, I can ping a WLAN client or hit a wireless web cam for that matter on port 80.  If I am using a WLAN client, I can access LAN clients just fine.  The problem lies with WLAN clients not being able to access other WLAN clients.

    Is this just not possible?  I'm thinking surely it is.  I have even went to just one DHCP pool and disabled the WLAN pool.  Still WLAN clients could not ping or access other WLAN clients while setup in this mode.

    steps taken:
    I have restored to 'factory defaults' without any luck to remedy the problem.

    Is there just a problem with the interface itself? ???



  • okay - I think I figured this out.  on the WLAN interface, I checked 'Allow intra-BSS communication'.



  • Yeah that's it, clients can't communicate between each other without that.

    Now I re-read the WLAN config page I see that … thanks.  However, reading the manual (P366, sec 18.3.1) appears to suggest that BSS must be turned off if the WLAN is bridged ... so I've had it turned off since setting up the WLAN and I've been scratching my head about this for a year or more now.

    That's referring to BSS and IBSS modes, you're using hostap mode.
