Network Interface Problems for DomU Firewall
I am attempting to setup a firewall in a DomU. The firewall program I
eventually want to run is Shorewall.
Both my Dom0 and DomU are Debian Lenny 64 bit systems. The Dom0 has four
physical network interfaces installed. Currently, one of the NICs is hidden
using the pciback.hide command in the /boot/grub/menu.lst file. Similarly,
the hidden NIC is passed to the DomU using the pci =

DOMU loses outside connection
When I start xen dom0 I get that same dhcp address for eth0 and for
xen-br0, dom0 can talk to the world. If I start each of my 3 domU''s
mannually, each guest gets a xen-br0 vif with a dhcp address and all 3
can talk to the outside world and each other (my "flat network").
What I want is a tiered network with the first domU acting as a firewall
with 3 nics

routing problem with domU bridged to two networks
As I received no response on the general CentOS list, I'll repost it
here as the question is about Xen virtual machine routing.
This is my network setup:

Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network

help seeing DMZ from LOC
I have a three interface network (net,loc,dmz).
The internet interface (eth0) has a static IP.
Windows machine in the local network (eth1) use DHCP to get IPs from
the 192.168.10.0/24 netblock.
The Debian machine in the DMZ (eth2) gets a fixed IP through DHCP in
the 192.168.11.0/24 netblock.
The DHCP server is running on the firewall machine (not ideal, I know,

Proxy Arp
Hopefully this is an easy question....
I''m using a leaf router (bearing) running shorewall. Three interfaces net,
loc, and dmz. Only one computer in the dmz and its being proxy arp''d.
External and internal (net and loc) can reach the dmz but the dmz cannot
reach the isp''s gateway and beyond, but can reach a system adjacent to the
firewall.

RE: Setting up a routed DMZ -CLOSED
My sincere apologies to all on this list. After looking for returning
packets with tcpdump and not finding ANY I called our provider to
confirm our IP assignment. The IP range that I was given by my boss was
incorrect. After adjusting the ip assignments, everything is working
perfectly. Thank you all for your time in troubleshooting this, and I

Xen 3.2.1 and large traffic problems
Hello,
I am having a issue with my Xen setup, that other people have reported
as well. No one seems to have a solution to this problem or an idea
what might cause it. My only hope is that I might get some more ideas
here in the devel list.
The basic problem is that if there is sustained high data rate traffic
through a virtual interface, it seems that the queues fill up and the

SAMBA & ISAM Databases

I have disabled "opplocks" in both Win9x clients and on the Samba share.

Setting up a routed DMZ
Hello all,
I''ve read the shorewall guides and browsed through the mailing
lists, but I haven''t been able to find out if the following is possible
or not using shorewall.
Our provider has given us 16 IPs + 4 in a separate range for our uplink.
I would like to replace that router with a Linux box running shorewall
with three interfaces. I want the DMZ to be a standard, routed

Giving a domU direct access to a NIC
Hello,
I am experimenting with Snort and other IDS and I would like to use Xen for
these tests. This would require me to use port mirroring to sent a bunch of
packets to a NIC located on my Xen machine.
I don''t really know how Xen networking works, but is it possible to give a
domU direct access to a NIC ? Or at least give it enough access so that it
can see packets that are not for the

Is ProxyARP or NAT entries really neccesary for DNAT to work?
I have been trying to get DNAT to work and I actually have succeeded
too, however, not how I thought it would work when reading through the
documentation.
1. No matter what I do I cannot get DNAT to work unless I have an entry
in eiter the nat or the proxyarp file. Is that really how it''s supposed
to be? I can''t find anything about it in the documentation.

Not sure how to configure Shorewall 2.1.3
I have an access-IProm my isp that I configured my eth0 with.
And I also have an IP-range assigned from my ISP that will be used on my servers connected to eth1. The IP-range is routed thru the access-IP.
This is how my configfiles look like. Internal everything seems to work but not external.

Unable to allocate dma memory for extra SGL
Hi all;
We have a Solaris 10 U9 x86 instance running on Silicon Mechanics /
SuperMicro hardware.
Occasionally under high load (ZFS scrub for example), the box becomes
non-responsive (it continues to respond to ping but nothing else works
-- not even the local console). Our only solution is to hard reset
after which everything comes up normally.

Proxyarp vs DNAT
Hello list,
I am in the process of switching from IPCOP to Shorewall s the firewall
for our small office. I very much like the fact that Shorewall runs on
top of the same OS (openSuSE 11.4) that I run on the server and my desktop.
Our setup is fairly straightforward. We have 8 static ip addresses from
our ISP, which provides a cable modem and a Cisco 800 series router.
The ip addresses are
