Hi all!

I've an AMD Athlon X2 3800+ operating as gateway/firewall (dom0) for my
LAN. Below an scheme of it:

                                          _____
                                     ____/     \____
          +---------------+         /               \
          | Bridge/Router +---------|    Internet   |
          +-------+-------+         \____       ____/
                  |                      \_____/
                  | eth0
           +------+-------+
           |  Gway / FW   |
           +------+-------+         8 x 10/100 mbps          _____
                  | eth1              +--------+        ____/     \____
                  |                   |        |       /               \
                  +-------------------+ Switch +-------|      LAN      |
                                      |        |       \____       ____/
                                      +--------+            \_____/


I'd like to have severals domUs to take advantage of this hardware. The
Internet connection is via PPPoE by means of eth0. This is
/etc/network/interfaces from gateway:

------------------------------------------------------------------------
alderamin:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static

auto eth1
iface eth1 inet static
       address 10.1.0.10
       netmask 255.255.255.0
       network 10.1.0.0
       broadcast 10.1.0.255

# To PPPoE
auto dsl-provider
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up
provider dsl-provider
------------------------------------------------------------------------

But when I start xend, I lose the Internet connection and the LAN
connectivity from the gateway. This can be due to any conflict with Xen
bridge? This is xen-config.sxp that I was using:

alderamin:~# cat /etc/xen/xend-config.sxp |grep ^[^#]
network-script 'network-bridge netdev=eth1')
(dom0-min-mem 196)
(dom0-cpus 0)

Thanks in advance.

Regards,
Daniel
