Duplicate traffic using tee ipfilter command

[Jbrjbr]

Hi there,

first of all, i just love merlinwrt! Thanx for the excellent work.

I have a question on an ipfilter module. I want to capture and duplicate traffic using a command like this:
iptables -t mangle -A PREROUTING -p tcp --dport 1935 -d 192.168.0.200 -j TEE --gateway 192.168.0.201

(i want to capture and duplicate traffic that my weatherstation is sending to weatherunderground).

However the command fails saying "missing target/chain/host".

It turns out there is a probably a module missing. I did some searching on the internet if i could "insert" that module myself but i found, since this is a kernel module, it has to be provided in the firmware itself....

Anyone know is if this is correct? And if so... is there workaround of some sort to duplicate traffic on the router?

Ciao,
Jbr

Try adding:

modprobe xt_TEE

What router model? What firmware version?

Oops.. sorry, my mistake. Firmware: 318.13_0 (latest), model Asus AC3200

For some reason I cant connect using my VPN right now, so cannot do the modprode command....
Edit: the command responded with blank/nothing.
Edit 2: well, that did the trick! I can see the modules is loaded using lsmod. Thank you for your help!
