Here it is (was moderated because of attachment) :

Hello,

I this is not a problem with my shorewall configuration but strange
logs that I'd like to understand, so sorry for being a little
offtopic.

I have setup a xen machine (debian lenny + shorewall 3.2) with bonding
and vlans following the attached schema (or here :
http://i39.tinypic.com/esstqc.png)

As soon as I launch my first domU in vlan 2, I get a lot of traffic
aimed at other machines (and not broadcast) that is dropped.
I find it strange to receive all that junk, and wondered if someone
could tell me why it happens ?

here a /etc/network/interface extract for br2 :

iface br2 inet manual
     up ifconfig bond0.2 mtu 1492
     bridge_ports bond0.2
     bridge_fd 1
     bridge_hello 1
     bridge_stp off


Would anyone have an idea about why this happens ? Is this something
inherent to bridges I have not understood ? Or should I better look at
the switches ?
