# nft add rule inet filter divert ip daddr 0.0.0.0/0 meta l4proto tcp tproxy to :2000
Error: conflicting protocols specified: ip vs. unknown. You must specify ip or ip6 family in tproxy statement
add rule inet filter divert ip daddr 0.0.0.0/0 meta l4proto tcp tproxy to :2000
~~~~~~~~ ^^^^^^^^^^^^^^^
instead of:
# nft add rule inet filter divert ip daddr 0.0.0.0/0 meta l4proto tcp tproxy to :2000
Error: Conflicting network layer protocols.
add rule inet filter divert ip daddr 0.0.0.0/0 meta l4proto tcp tproxy to :2000
^^^^^^^^^^^^^^^
