[Pkg-xen-devel] Bug#571634: [xen-utils-common] using --physdev-out in the OUTPUT, FORWARD and POSTROUTING
Package: xen-utils-common Version: 3.4.2-3 --- Please enter the report below this line. --- After several tests and many hours of investigation I found out that this is not a bug. The iptables rules that triggers the message is found in /etc/xen/scripts/vif-common.sh [1], but as the syslog message clearly indicates this rule works perfectly when the traffic is bridged. Moreover, those rules are intended for setups where the default policy for FORWARD is other than ACCEPT. I think that message is a bit misleading, but if it's to be considered a bug it should be reported against iptables. AFAIK iptables isn't capable of guessing if the traffic is bridged or routed so it has to show the message anyway. And if it's routed the rule is inserted without failure, it just never matches anything. My problem with the DomU not forwarding traffic is still unresolved, but now I'm sure it has nothing to do with this. I apologize for the noise. Regards.
