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 -

[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.
Does this

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,

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

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
installed and to start our first virtual host.
I''ve got one outstanding issue with iptables that is preventing me

This is a colo''d server. It has s single NIC with public IPs.

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

my notes on bond, bridge, network, kvm, host and virtual so far
I put this page together just so I won't spam the board anymore begging
for help..lol

This shows a working effort of bonded eths, bridged into a vm, and a few
other things.
The only missing thing is something on the host that ends up putting the
VM internet
connection into some kind of limbo.

Networkfilters in Routed setup
Hello!
Since i could not find any information on the internet about this subject, i'm going to try my luck on this list.
I'm trying to setup network-filter on a routed setup. I have a root-server at Hetzner, a german hosting provider.
Along with my server i ordered a (/28) subnet to be able to setup dedicated IPs for my virtual machines (KVM).

KVM with bridge in one interface
Hi,
I have only one ethernet port in a remote server. (eth0)
I have a public address with x.x.x.164 netmask 255.255.255.240 gw x.x.x.161
and want to use in my guest OS the next available ip address (x.x.x.165 netmask 255.255.255.240 gw x.x.x.161)
Is this posible with brctl to achieve this?

Getting nwfilter to work on Debian Wheezy

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

an additional subnet 192.168.128.160/28 routed to its main address
192.168.17.125.
The host's subnet is configured as bridge
