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?? Thanks
