[Bridge] Bridging partially (rx eth0 -> tx eth1)

Hi there,

I'm new on the mailing list, but this is not a good reason to be quiet :-).
I'm very interested in the bridging functionnality of the Linux kernel.
I am wondering f it is possible to bridge "partially".

I mean : I would like to have all the traffic from the RX of my eth1 card  
directly sent out through the TX of my eth0 card.
But I would like to receive the frames from the RX of eth0 thanks to a  
PF_PACKET socket.

Is this possible with the bridging system ?
I don't think so, but I haven't foud out the answer...

Thanks in advance !
Best Regards.
JM

ebtables can select which traffic gets bridged.

Thnks you for answering.
AFAIK, ebtables works like iptables, but within the L2 layer ?
This means I could eventually send only IP (and VLAN) traffic to the host,  
and forward everything else ?

I am still looking at the doc.
