Hi there, I'm Alan.

2nd day I'm trying to set up network in Xen. Firstly, I set up it via bridges and it have worked in some success ;-) But bridges is not what I want.

So, I decide to reconstruct network with routes. I set up everything as many tutorials said, but nothing happens: I can't ping domU from host and can't ping dom0 from guest ;-(

So, below, I will show what I'm doing, I would like to hear what I'm doing wrong.

Thanks for your patience.

================
Dom0 have one (1) working net card: eth0

with IP for external LAN: 10.9.3.92
and gateway for with IP: 10.9.3.1

---------
My xend-config.sxp have:

(network-script network-route)
(vif-script vif-route)

---------

%# cat /proc/sys/net/ipv4/conf/all/proxy_arp
1
%# cat /proc/sys/net/ipv4/conf/eth0/proxy_arp
1
%# cat /proc/sys/net/ipv4/ip_forward
1

---------

In my %.vm (Virtual Machine) file I have:

vif  = [ 'ip=10.0.2.2' ]

--------

In my DomU (Windows in my case) I set up network interface as follow:

address 10.0.2.2
netmask 255.255.255.0
gateway 10.9.3.1  # it's a gateway which gave me ISP (see above)

========
After "xm create ...":

--------

%# ip r
[...]
10.0.2.2 dev vif2.0  scope link  src 10.9.3.92
[...]

-------

The last line is doesn't matter

---------

%# iptables -L

===========

from Dom0:

%# ping 10.0.2.2
PING 10.0.2.2 (10.0.2.2) 56(84) bytes of data.
From 10.9.3.92 icmp_seq=2 Destination Host Unreachable
From 10.9.3.92 icmp_seq=3 Destination Host Unreachable
From 10.9.3.92 icmp_seq=4 Destination Host Unreachable

from DomU:
%# ping 10.9.3.92
ping time out
ping time out
ping time out
ping time out

Also in Dom0:
%# tcpdump | grep 10.0.2.2
shows nothing ;-(

=========

Thank for patience.

P.S. Gentoo user ;-)
