Hacking Packet Mirroring

[gudenau]

I have a Wii U with a LAN adapter connected to a Switch running DD-WRT, this switch is directly connected to my PC. I would like to make the switch send all Wii U packets to my PC for analysis, I have attempted to use "iptables -t mangle -A POSTROUTING -s [WIIU] -j ROUTE --tee --gw [PC]" and "iptables -t mangle -A PREROUTING -s [WIIU] -j ROUTE --tee --gw [PC]" with the proper IP addresses but Wireshark does not pick up any packets from the Wii U. What am I doing wrong?

Why not use a crossover cable?

Why not use a crossover cable?

Because I only have one LAN port on my PC.

You can still sniff the traffic over the crossover cable.

How? There would be no way for the Wii U to get out if it is connected to my PC.

Do you not have WiFi?

Do you not have WiFi?

No.

If I want to do this, I might just get a multiport PCI-e NIC and make a wiretap.
