Connection tracking, DNAT, and boot sequence
Greetings shorewall users,
I''m running into a problem and hoping someone might have a simple idea
how to fix it.
I have shorewall configured on a linux fw with 2 port DNAT rules to an
internal server for openvpn from external clients. Everything works fine
there.
I have a problem when the fw is rebooted however. When it comes back up,
interfaces are brought up before shorewall is

Dual-homing BGP gate problem
Hi Tom,
After two weeks of nightmares I decided ask You (and anyone reading this mail).
Context is as follows:
I try to update system on my central router from kernel 2.6.29.6 and Shorewall
4.2.6 (old) to kernel 2.6.31.6 and Shorewall 4.4.4.2 (new).
This is LiveCD image boot (Devil-Linux distribution compiled by me), so config
is this same.
I have established ten OpenVPN tunnels and two

VLAN martians
I''m playing around with VLAN''s and I have a VLAN capable (layer 2) smart
switch. I see a steady stream of martians in the logfile if I have the
routefilter option set on the loc zone interfaces in
/etc/shorewall/interfaces. I have two interfaces in the loc zone, eth1
and vlan2 respectively. vlan2 is an 802.1q trunk going towards the switch.
Is this the expected behavior in

I want to use lastest version of Shorewall in my fresh debian squeeze
instalation,

Can I use shorewell stuff for my problem
Hi all, Im new to shorewell, can anyone guide me whether I can use
shorewell for my work.
I have a requirement in our work:
Each system shall have two Ethernet card interfaces(system means hardware
devices, servers, clients in other words any device or host used in the
project). The IP address of each interface will be of different networks,
subnets and gateways completely. Bcoz if one of

Shorewall 4.4.6 and Multiple ISP with 2 routed subnets
Hello,
I have 2 ISP uplinks (zones: inet1 and inet2), each with a fixed IP on the outside and a routed subnet (/25 and /26) on the inside. So, behind the firewall i have 2 networksegments (lan1 and lan2) with public IP-addresses. The segments are completely isolated from eachother: hosts in zone "lan1" connect only to "inet1" and hosts in zone "lan2" only connect

Xen networks running in Promiscuous modes
Can I ask you a quick question? I''ve set up bridge-networking for Xen 4.1 (xen-4.1.3-25.el5.22) and networking was being done properly for Dom0 and DomUs. However, I
noticed that Dom0 receives a lot of network interrupts or network
packets even when they were not actually meant for either Dom0 or DomU.
Now, here are the questions:
1. Dom0 is acting in promiscuous mode, right?

Configuring eth1 to be in promiscuous mode
Hi there --
I want to have eth1 on my system run in promiscuous mode. I modified the
/etc/sysconfig/network-scripts/ifcfg-eth1 file to read as follows:
DEVICE=eth1
BOOTPROTO=
...
ONBOOT=
TYPE=Ethernet
...
I reboote the system and when I did an /sbin/ifconfig, eth1 appeared without
an ip address. I did a check in the /var/log/messages file and while eth0 is
in promiscuous mode, eth1 does not

sometimes after a reboot the complete network is down

Xen''s interface in promiscuous mode
Hello all,
Playing with Xen on GNU/Debian Lenny, I just discovered that all my
virtual network cards are in promiscuous mode by default.
Changing that manually does not seems to change anything (that is,
everything still works great).
Is there any reason to have virtual network cards in promiscuous mode ?
And where can I change this default behaviour ?
Thanks,
JB

[XCP] promiscuous mode for vif
Good day.
Found strange behavior in PV-domains. Application like tcpdump or iftop
require promiscuous mode for interface. And this feature is disabled by
default, as I understand.
message from iftop:
pcap_open_live(eth0): eth0: You don''t have permission to capture on that
device (socket: Address family not supported by protocol)

Multicast only working in promiscuous mode
Hi,
I am trying to set up a uPnP server on a Linux box (Debian Sarge Stable kernel 2.6.8). uPnP
works using multicast packages for locating servers.
This does however seem to fail unless I set the relevant NIC in promiscuous mode. If I do so,
it works well.
I have added
ip route add 224.0.0.0/4 dev eth0
and

vmware promiscuous mode
As a heads up to everyone, VMware requires you to take special
precautions when trying to put a virtual nic into promiscuous mode,
which is required for Xen networking to work.
I spent a fair amount of time diagnosing Xen network problems when it
wasn''t Xen at all. As I was just beginning to learn Xen, I was
convinced it was something I was doing wrong, when it wasn''t at

Setting up softflowd - set promiscuous or not?
Hi List,
I''m in the process of setting up softflowd 0.9.9 on a Centos 6.4 system
(compiled from source tarball).
The daemon will listen to an unused interface that is receiving port
mirrored traffic (a.la. Span port)
I am planning on using the softflowd init script and sysconfig file
provided in the tar ball.
Do I need to manually put the unused interface into promiscuous mode, or
