Hmm, works for me: table ip raw { chain prerouting { type filter hook prerouting priority -300; policy accept; udp dport 53 notrack } gets exported as: nft -j list ruleset {"nftables": [{"metainfo": {"version": "0.9.1", "release_name": "Headless Horseman", "json_schema_version": 1}}, {"table": {"family": "ip", "name": "raw", "handle": 1}}, {"chain": {"family": "ip", "table": "raw", "name": "prerouting", "handle": 1, "type": "filter", "hook": "prerouting", "prio": -300, "policy": "accept"}}, {"rule": {"family": "ip", "table": "raw", "chain": "prerouting", "handle": 3, "expr": [{"match": {"op": "==", "left": {"payload": {"protocol": "udp", "field": "dport"}}, "right": 53}}, {"notrack": null}]}}]}
