Yep, packets should be going through iptables as they traverse the
bridge in Dom0 (as the diagram shows), unless it's explicitly disabled.
What does:
$> sysctl net.bridge.bridge-nf-call-iptables
show? (It should be "1")
It is showing "1". Based on my iptables logging, I do see the packet going through iptables' Magle and Nat Prerouting chains. It then goes into ebtables' Filter Input chain, and then there is no more logging.
Thanks, David
