[Xen-users] Gateway/firewall with Xen

[Daniel Bareiro <daniel-listas@xxxxxxx>]

Hi all!
I want to migrate my gateway/firewall to dom0 or domU. I tried the
following configuration to migrate my firewall/gateway to dom0:

--------------------------------------------------------------------------
cat /etc/network/interfaces
# The primary network interface
auto eth1
iface eth1 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255

# DSL interface
auto dsl-provider
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth2 up # line maintained by pppoeconf
provider dsl-provider

auto eth2
iface eth2 inet manual
--------------------------------------------------------------------------

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

But any domU I created get unreachable to the Internet or the others
PC's of the LAN, and dom0 can access to Internet y can't to reach to the
others PC's of the LAN. These are the domU's config files:

cat /etc/xen/domU.cfg |grep ^[^#]
kernel  = '/boot/vmlinuz-2.6.18-4-xen-686'
ramdisk = '/boot/initrd.img-2.6.18-4-xen-686'
memory  = '128'
root    = '/dev/sda1 ro'
disk    = [ 'phy:vm/firewall-disk,sda1,w', 'phy:vm/firewall-swap,sda2,w' ]
name    = 'domU'
vif     = [ 'mac=aa:cc:00:00:00:02, bridge=xenbr0' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

cat /etc/network/interfaces |grep ^[^#]
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
 address 192.168.1.10
 netmask 255.255.255.0
 network 192.168.1.0
 broadcast 192.168.1.255
 gateway 192.168.1.2


Another alternative is to migrate the firewall/gateway to domU, but I'm
not sure of the network configuration to use even.

I would appreciate anybody can help me with this issues.

Thanks in advance.

Regards,
Daniel
