blocking traffic on the FORWARD chain using physdev
Currently using physdev on a bridge to try and isolate certain paths
across and to the bridge. It all works except when trying to stop the
flow in one direction on the FORWARD chain?? Can someone please help??
Below is the testing done so far.
eth1 <---> BRIDGE <---> eth0
# Block (eth0 ---> eth1) - blocks both directions and not just one??
iptables -A FORWARD -m physdev

Shorewall 4.0.0 Beta 4
I''ve uploaded Beta 4. It corrects a bad bug involving exclusion in the
hosts file. In addition, it contains the first release of a new
Bridge/firewall implementation that uses the reduced-function physdev
match found in kernel 3.6.20 and 3.6.21.

filter policy drop and allow transparent proxy
Trying to use the policy drop rule with the bridged firewall, when I
removed the first line the transparent proxy works great? It seems a
bit strange as from reading several articles on it I thought the
following occurs.
1st line - if it doest match it gets dropped on the local filter input.
2nd line - redirects the traffic off the link layer into the network
layer ready for line 3.
3rd line -

Bug#571634: bridge loosing connection
Hi,
I'm not sure but I think I suffer under the same problem with a bit
different setup with squeeze testing and xen 4.0rc5.
In fact I'm using bridges in the dom0 and the connections to the domU
get lost sporadically.
In don't see where's a solution to the problem... Is it now a bug? When
it's an iptables bug, where's the corresponding bug in the iptables

[Bridge] Clarification regarding device matches in bridge-netfilter
Hi folks,
in 2.4 kernels, device matching for bridged packets was done with
iptables -i/-o. Since 2.6, I was used to use -m physdev here.
In 2.6.18, This seems to be more complicated. At least the filter/INPUT
chain now doesn't match with -m physdev --physdev-in anymore, but
FORWARD and OUTPUT does. I also read the note that -m phydev is now
deprecated for non-bridged traffic.

so close! just an iptables rule away.....?
Hi,
I''ve been making leaps and strides with Xen on FC4. It has been easy to get

I''ve got one outstanding issue with iptables that is preventing me
progressing further.
This is a colo''d server. It has s single NIC with public IPs.
The bridge is set to come up binding vif* <> xen-br0 <> eth1.

[Bridge] Multilink + bridge + nat problem

First of all my configuration:

Debian Squeeze hangs with kernel 2.6.32-5-xen-686
Hi all!
After upgrading to Squeeze, I am watching a Xen VMHost that after a
while it hangs. This did not happen when I was using Xen with Debian
Lenny (in this case as with Squeeze, the Xen components are from Debian
repositories).
In each case I connected a keyboard and monitor to the computer and the
screen remained black without answering any key.
This problem seems to also affect domUs,

Promiscuous mode
Hi Everyone,
In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created?
# Accept packets leaving the bridge going to the domU only if
# the destination IP for that packet matches an authorized IPv4
# address for that domU.
iptables -A FORWARD -m physdev --physdev-out vif1.0 \
--destination 216.146.46.43 -j ACCEPT

vif-common.sh and iptables
Hey everyone,
I have a question about vif-common.sh. I run multiple bridges attached
on dummy interfaces, which allow me to put guests in seperate subnets
(routed through the dom0). As you might expect I already have quite
extensive iptables scripts to accomidate this kind of routing.
I was just hoping someone on this list can confirm, that I understand
what the iptables lines in vif-common.sh

Getting nwfilter to work on Debian Wheezy
Hi,
I'm trying to configure nwfilter for KVM, but so far I haven't managed
to figure out a working configuration.
Network setup: The dom0 (Debian 7.1, kernel 3.2.46-1, libvirt 0.9.12) is
connected via eth0, part of the external subnet 192.168.17.0/24, and has
an additional subnet 192.168.128.160/28 routed to its main address
192.168.17.125.

Missing packets on Dom0 when sniffing bridge with wireshark/tethreal
Hi,
I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own

through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2
The scenario:

that are sending SIP stuff to Dom1, but fail to capture any packets. I

xenbr0 / domU static IPs
Hi, I have a new xen hosting platform. I have given the bridge a static IP which I can ping/ssh to etc, when I create a new vm all works well apart from the networking. If I give DomU a static IP I can''t ping out from the box, Dom0 can''t ping the vm. I''m suspecting it just isn''t seeing the bridge but am unsure where to start looking. This is a very standard
