Finally, disabling generic-receive-offload fixes the whole mess :) Tom, maybe you could update the FAQ like this: - ethtool -k ethN tso off gso off + ethtool -K ethN tso off gso off gro off (Note the -K instead -k as well) Of maybe even like this to be sure: ethtool -K ethN tso off ufo off gso off gro off I'm wondering if it would make sense to integrate some means into shorewall to handle offloading on all devices where tc rules apply?
