ethernet port mirroring and sniffing

Hi All,

  actually I deployed a 3500lv2 as Wifi bridge to work on network devices. I would like to mirror the entire traffic (wired/WIFI ) on a dedicated ethernet  port to sniff it on a monitoring and capture host.

 Ufortunatly the only example I found is iptables mangle witch not does doing the job ( no traffic is redirected to my host ):

iptables -A PREROUTING -t mangle -j ROUTE --gateway 192.168.1.11
iptables -A POSTROUTING -t mangle -j ROUTE --gateway 192.168.1.11

 

An this is not what I execpt , what I exepect is is more a physical port mirroring whereas WLAN traffice is listened .

Today routeur is running TomatoUSB 1.28 and is configured as Wireless ethernet bridge.

 

Do you know how to mirror all traffic on a dedicated phycal port ?

 

Thank you .
