    I am having problem in ping or connect AP from Mobile Node(essid & channel is the same,maybe routing did
    not set properly but i fail to configure with route add default gw 192.168.3.4,its alway said
    network is unreachable ),My Mobile Node is using acx100 as driver while AP(redhat 9.0) is using
    HOSTAP 0.1.3.Any one can help? I heard How-To said we not need to set address on eth0 & wlan0 if
    we have bridge(with address)but will MN connect straight with bridge that i set?

    My mobile node setting:
