RT-AX56U v1 port mirroring / SPAN not working (iptables: No chain/target/match by that name)

Model: Asus RT-AX56U v1
Asuswrt-Merlin: 386.3_2


SPAN / port mirroring not working

# iptables -t mangle -A PREROUTING -j ROUTE --gw 192.168.1.14 --tee
# iptables -t mangle -A POSTROUTING -j ROUTE --gw 192.168.1.14 --tee

iptables: No chain/target/match by that name.

The above commands worked on Asus RT-AC3100 (Asuswrt-Merlin: 386.3_2)

Don't use ROUTE use TEE.

modprobe xt_TEE
iptables -t mangle -A PREROUTING -j TEE --gateway 192.168.1.14
iptables -t mangle -A POSTROUTING -j TEE --gateway 192.168.1.14
