MultiWAN + Bridge + Sticky OFF == kernel: arpresolve: can't allocate llinfo for



  • Hi, I'm currently using 2.0-rel on an Alix 2D3.
    My setup is a bit weird, but seems to somehow work ok.

    ISP1
    ADSL
    MGCP VoIP for 10 phones
    IP: 10.0.10.254
    Runs a dhcpd + tftp for the VoIP phones, it's traffic must passthru.
    We want to use this provider only for VoIP and as a backup provider

    ISP2
    SDSL
    Static Public IP
    We want to use this provider as main incoming and outgoing to the world

    pfSense
    LAN (10.0.10.251 - bridged to WAN)
    WAN (10.0.10.250 - bridged to LAN)
    OPT1 (x.x.x.x - Static Public IP)
    One Gateway Group is set with WAN GW + OPT1 GW == GWG1
    LAN Firewall rules: set to limit outgoing traffic, and redirect some portions of it (HTTP, MAIL) via GWG1 - work as expected
    WAN Firewall rules: set to allow * incoming (might be changed later), mainly to ensure the dhcp gets in, so the MBCP phones can work correctly
    OPT1 Firewall rules : set to block *, since this is a Public IP !
    No sticky connections set (!!!!)

    Symptom
    kernel: arpresolve: can't allocate llinfo for 10.0.10.254
    kernel: arpresolve: can't allocate llinfo for 10.0.10.254
    kernel: arpresolve: can't allocate llinfo for 10.0.10.254
    kernel: arpresolve: can't allocate llinfo for 10.0.10.254

    Now i found this bug report : http://redmine.pfsense.org/issues/337 that has the same symptoms except …
    !! I have sticky connections turned off !!
    Aside these messages everything -seems- to work fine (only 24hrs i deployed this in production ..)

    So what can be the issue ?

    Is my setup THAT weird ?

    Note here are a few extra notes regarding my setup:

    Caveat
    Since it's ISP1 that is pushing dhcpd infos, it's pushing itself as default GW to all network gear, so if ISP1 fails, no more net.

    Forthcoming upgrades
    ISP1 needs to have it's dhcpd push data to the phones, i'm planning to setup a dhcpd conf on pfsense that would forward all dhcpd queries from the phones to the ISP1, and address all others itself, so pfsense can server as dhcpd and main GW for the LAN network gear.

    Please comment..

    Every advise is good !
