    I've got a bit of a mystery when I have the below picture

                                         fxp1
              10.1.x.x/22 ______|___ 10.1.x.x/22
    |device|-------|switch| ---------| bridge | -----------|targ|
                                 fxp2 fxp0

    arp replies from the target are not being forwarded to fxp2
    if I remove the switch (a cisco cat) and go to the picture
    below

                                         fxp1
              10.1.x.x/22 ______|___ 10.1.x.x/22
    |device|-------------------------| bridge | -----------|targ|
                  x-over cable fxp2 fxp0

    the arp replies are recieved just fine. I've tried both 5.2.1-p8 and 5.2-current.
    Additionally, if targ is a bsd box things are OK, but if targ is a unixware box
    which it needs to be, bzzzzt.

    ------------
    net.link.ether.bridge_cfg=fxp0,fxp2
    net.link.ether.bridge.enable=1

    I've tried both
    net.inet.ip.check_interface=[0|1]

    ifconfig_fxp0="inet 10.1.X.X netmask 255.255.252.0 media 100basetx mediaopt full-duplex"
    ifconfig_fxp2="media 100basetx mediaopt full-duplex"
    ifconfig_fxp1="inet 10.5.Y.Y netmask 255.255.255.0 media 100basetx mediaopt full-duplex"

    any insights or I ideas?

When things can't get any worse, they simplify themselves by getting a
whole lot worse then complicated. A complete and utter disaster is the 
simplest thing in the world; it's preventing one that's complex.
