I am trying to set up a domu as firewall / router. After several failed attempts with network bridges, I tried the hardware passthru to DomU.

/boot/grub/menu.lst
module (...) pciback.hide=(05:01.0)

lspci (dom0):
05:01.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100

/etc/xen/domU.cfg:
extra       = 'swiotlb=force'
pci         = [ '05:01.0' ]
vif         = [ 'mac=00:16:3E:0C:AF:F1, bridge=eth0' ]

lspci (domU):
00:00.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100

After running "pppoeconf eth1" I geht the message (syslog): "eth1 up...". an everything worked.

But when I restart, the pppoe-connection fails with the error: "network down". After running "ip link set eth1 up" and "pon dsl-provider" manually the network "comes up" and everything works. Any suggestions what I have to do in order to start the network autmatically after reboot?
