Hello Andy,

thank you very much for taking the time to read my mail.

Sorry, I used the * just for not making my ip address public when I post
 to the mailinglist. It has fixed value.

I am wonder why this setup does work properly on gentoo domUs but not on

Here is my gentoo domU ifconfig+route
eth0      Protokoll:Ethernet  Hardware Adresse 00:16:3E:2F:62:C2
          inet Adresse:78.47.*.210  Bcast:

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          Kollisionen:0 Sendewarteschlangenlänge:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
route -n
213.239.*.45 UH    0      0        0 eth0       U     0      0        0 lo         213.239.*.45         UG    0      0        0 eth0

My mission seems to be to get just that on debian too.
I must admit that the network setup looks crazy, but why the hell does
it working on gentoo domUs.

Sorry for my bad english
and thanks again
