Hello, I'm working on traffic shaping with tc and have some old iptables rules with which I've tried to use iptables-translate to convert legacy instructions to nftables. For example, I have the following: iptables -t mangle -A OUTPUT -p tcp --match multiport \ --sports 22,1965 -j MARK --set-mark 100 and the result is, nft add rule ip mangle OUTPUT ip protocol tcp \ tcp sport {22,1965} counter meta mark set 0x64 However, nftables does not like that as-is and responds with an error: "Error: Could not process rule: No such file or directory" I've obviously missed or misinterpreted something there. What would be the correct nft instruction(s) including any prerequisites? Or what traffic shaping guides are there for nftables with concrete examples? I've pored over the wiki and it is great for the aspects which have already become familiar but it is far too abstract for me for new areas. $ uname -sr Linux 5.10.63-v7l+ $ apt-cache policy nftables | head -n 2 nftables: Installed: 0.9.8-3.1 Thanks.
