It seems like the issue has been resolved with the next command. However, I’m not sure if it’s okay because it seems more like an imitation rather than actual mirroring

ip netns add dup
ip link add name dup1 type veth peer netns dup name ens3
ip link set dup1 up
ip -n dup link set ens3 up
ip address add 10.10.10.1/24 dev dup1
ip -n dup address add 172.16.1.202/24 dev ens3
ip -n dup route add default via 10.10.10.1
sysctl -q -w net.ipv4.conf.dup1.rp_filter=2. (=>0)
ip netns exec dup sysctl -q -w net.ipv4.conf.ens3.forwarding=1
iptables -t mangle -A PREROUTING -i ens3 -p udp --dport 4789 -j TEE --gateway 10.10.10.2
iptables -t raw -A PREROUTING -i dup1 -p udp --dport 4789 -j CT --zone-orig 1
iptables -t nat -A PREROUTING -i ens3 -p udp —dport 4789 -j DNAT —to-destination 172.16.1.47:4789
iptables -t nat -A PREROUTING -i dup1 -p udp —dport 4789 -j DNAT —to-destination 172.16.2.10:4789

Any better idea?
