I found an interesting article here :

http://www.mail-archive.com/shorewall-users@lists.sourceforge.net/msg11831.html

"One reason for running a bridge is that you are using KVM. On FC15 with
KVM under libvirt, you must include this in your /etc/shorewall/init file:

        echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables

Beginning with Shorewall 4.4.20, Shorewall will set that for you when
you define an interface with the 'bridge' option."

Hi, do you filter traffic between vm in the same bridge ?

Hi, 

sorry if this is a dumb question, but what happens with this patch applied when 
i use i.e. shorewall to filter on a bridge (vmbrXY)? 

Thanks
