Hi, I have just configured a Linux box with kernel 2.6.16.7 and configured two ethernet interfaces (with MTU 1500) in bridge mode. CONFIG_BRIDGE_NETFILTER is enabled. The problem is that ping -s 1500 192.168.0.2 doesn't work from 192.168.0.1 if the systems are separated by the bridge. Normal ping with smaller packet size works ok. What is wrong?
