Details - use bridge br-wan two network ports eth1 eth2

eth2 is connected to the pc, and eth1 is connected to the upper-level router

ebtables -t broute -I BROUTING -i eth2 -p ipv6 --ip6-proto 17 -j redirect --redirect-target DROP
ebtables -t broute -I BROUTING -i eth2 -p ip --ip-proto 17 -j redirect --redirect-target DROP
tcpdump -i br-wan host 2001:4860:4860::8888 -vvv
can’t get any dns request data
replacing -i eth2 shows dns requests. ipv4 has no such problems

does ipv6 not support redirect routing?
