Subject: Ignoring destination MAC address in incoming packets
Date: Mon, 08 Apr 2013 09:08:21 +0200	[thread overview]
Message-ID: <m3txnhmrdm.fsf@intrepid.localdomain> (raw)

Hi,

I have a bit unusual problem today. Is there a way to ignore destination
MAC address in incoming packets?

I need to do this on Atheros Wi-Fi. Basically what I need to achieve is
a sniffer.

Something like this:
- ATH5k working in ad-hoc mode, certain ESSID and channel selected.
- UDP packets in certain range are to be forwarded to other IPs.
- the wifi interface must be able to normally communicate (within its
  ESSID and channel).
- it has to work with iptables etc. (DNAT, routing).

I know I can change a line in the kernel (the one setting pkt_type to
OTHER_HOST) but perhaps there is some standard way for things like this?

Or should I use AF_PACKET and forward the data with userspace helper?

Any other idea?

TIA.
