Hello.

I should send you full report:
I have Linux 2.4.18, bridge-utils 0.9.5. My IP is 192.168.7.13.
I am pinging 192.168.7.1 - Linux machine.

I run following commands:
# ifconfig eth0 0.0.0.0
# ifconfig eth1 0.0.0.0
# brctl addbr br0
# brctl addif br0 eth0
# brctl addif br0 eth1
# ifconfig br0 192.168.7.13
To wait while bridge enters forwarding state:
# sleep 30
00:08:C7:49:4C:5C is MAC of eth0
# tcpdump -l -n -p -i eth1 -s 256 ether dst 00:08:C7:49:4C:5C > dst0 &
# tcpdump -l -n -p -i eth1 -s 256 ether src 00:08:C7:49:4C:5C > src0 &

00:80:AD:8A:98:17 is MAC of eth1
# tcpdump -l -n -p -i eth1 -s 256 ether dst 00:80:AD:8A:98:17 > dst1 &
# tcpdump -l -n -p -i eth1 -s 256 ether src 00:80:AD:8A:98:17 > src1 &
# ping -c 4 -n -w 10 192.168.7.1
# killall tcpdump

Results I get:
output of commands:
