Hi Florian, please is it a bug the rules did not work in the raw table or was it my configuration error? If it is a bug is it a bug of kernel or userspace? If it was my configuration error, should not be the rules moved to the filter table? How is it possible that using iptables-nft the rules are added to the raw table and it is working?
