If you want to ping that machine you need to allow responses,
So it is necesary to have something i ń iptables INPUT and OUTPUT 
If you have defautl in INPUT DROP than do not complane that it do not answer (when you want drop everything)
Even ebtables rules can drop everything, so be sure what you allow and what you denny

You didn't write anything about iptables setting.
This could be problem
what is your iptables setting ? Did you allow input and output for that ping
partner ?

Subject: [Ebtables-user] Bridge IP not anwering


Hello, 

I have set up a bridge with the following script that starts after the
network interfaces are started

BRIDGENAME="BRQ"
GATEWAY="192.168.0.1"
BRIDGE_IP="192.168.0.122"
BRIDGE_NETMASK="255.255.255.0"
STP_ON="yes"
STP_PRIO="1"
RETVAL=0

start() {
        echo "Starting service bridge"
       ifconfig eth2 promisc up
        ifconfig eth3 promisc up
        brctl addbr $BRIDGENAME  ||  return=$rc_failed
        brctl addif $BRIDGENAME eth2  ||  return=$rc_failed
        brctl addif $BRIDGENAME eth3  ||  return=$rc_failed
        ifconfig eth2 0.0.0.0  ||  return=$rc_failed
        ifconfig eth3 0.0.0.0  ||  return=$rc_failed
        brctl sethello $BRIDGENAME 1  ||  return=$rc_failed
        brctl setmaxage $BRIDGENAME 4  ||  return=$rc_failed
        brctl setfd $BRIDGENAME 4  ||  return=$rc_failed
        brctl stp $BRIDGENAME $STP_ON
        brctl setbridgeprio $BRIDGENAME $STP_PRIO
        ifconfig $BRIDGENAME $BRIDGE_IP netmask $BRIDGE_NETMASK up

        ip route flush cache
        ip route add default via $GATEWAY

But the problem i have is that i am not able to contact the bridge on its IP
192.168.0.122 i am running Centos 4.4 on a 2.6.18 kernel, i have tested this
setup on 3 different sets of network cards tg3, b44, via-rhine and in all of
them i have the same results no connection, i know the bridge is working
otherwise packets couldnt flow on the network, im using bridge utils 1.0.4-4

If any one knows what could be wrong??

Or does any one has a script or an example on how they set up their bridge
in order to be able to access it via its IP?? Do i have to use ebtables to
achieve this??


Thanks
