Hi Peter,

thank you for your reply.

My configuration looks like this:

/etc/xen/firewall.cfg
---------------
name = "firewall"

kernel = "/boot/vmlinuz-2.6.16-xenU-firewall"
root = "/dev/sda1"
memory = 256
extra = "gentoo=nodevfs"

pci = ['01:00.0', '02:00.0']

disk = ['file:/mnt/xenimages/firewall.xen,sda1,w']

#make network backend
netif = 1
vif = ['']


Now i have another DomU which i want to connect to the firewall.

/etc/xen/dgs.cfg
---------------
name = "dgs"

kernel = "/boot/vmlinuz-2.6.16-xenU"
root = "/dev/sda1"
memory = 256
extra = "gentoo=nodevfs"

disk = ['file:/mnt/xenimages/dgs.xen,sda1,w']

#use firewall as network backend
vif = ['backend=firewall']      


And this is not working, i can't connect the network to the firewall.

Regards
Matze
