Hi there!
Please help me with such problem:
I have bridge(s), kernel configuration is:
linux-2.4.17 + bridge-nf-0.0.5-against-2.4.17 + ebtablesv1.0_vs_nf-0.0.4
When i try "ping xxx.xxx.xxx.xxx -s 20000" the bridge hangs, when it
recieve first reply from xxx.xxx.xxx.xxx host. If host is not exsist, &
bridge do not get any reply, the command "ping xxx.xxx.xxx.xxx -s 20000"
works without hangups.
Thanks in advance!
Regards, Oleg.
