Hi,
I have an Asus AX56U with Asuswrt-Merlin 388.1 and I want to mirror all traffic to my Snort VM running on a Proxmox host.
When I set these iptables rules, the router immediatly freezes. It doesn't reboot, unless I do it physically, and all units on my network loose connection with everything.

Code:
modprobe xt_TEE
iptables -t mangle -A PREROUTING -j TEE --gateway <ip>
iptables -t mangle -A POSTROUTING -j TEE --gateway <ip>

What could cause this? According to my research, it shouldn't be too much traffic for the router to handle?
Any ideas how I could troubleshoot this would be grateful.
