You want to use different IPs for Dom0 and each DomU. It''s very simple, in each device you want to have a public IP, you configure it with the correct subnet mask, one IP from the range provided, and set the default gateway to the upstream providers router address. Eg, if the IPs provided are from 1.2.3.18 to 1.2.3.22 and the providers router is at 1.2.3.17, then you might configure Dom0 as : IP: 1.2.3.18, netmask 255.255.255.248, gateway 1.2.3.17 Your first DomU as : IP: 1.2.3.19, netmask 255.255.255.248, gateway 1.2.3.17 and so on. You would of course configure your Dom0 networking in bridge mode. There are other ways to set things up. Some providers will give you a /29 subnet, but route your traffic over a point-point link with a different /30 subnet. Sticking with the same subnet as above, you''d want to run in routed mode, with an outside interface IP to match the link and an inside interface in your 1.2.3.16/29 subnet. Yet another option is via proxy arp. You may be able to pick some info from these articles : http://shorewall.net/XenMyWay.html http://shorewall.net/XenMyWay-Routed.html They are how the author of the Shorewall firewall package configured his systems (two different ways) with similar requirements. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.

Current /etc/network/interfaces settings:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 193.34.X.88
netmask 255.255.255.128
gateway 193.34.X.1
auto eth0:0
iface eth0:0 inet static

address 93.104.X.231
netmask 255.255.255.128
gateway 193.34.x.1
..
.
.
ip''s are 193.34.X.88 and 93.104.x.230 - .233
Now all ip''s working. If i try 93.104 adress on domU.
Dom0 can acces net, but DomU not.
Off cource i remove other Virtual nic berore testing xen. (if try these
settings boot xen, eth0 gone)

Apologies, but I missed that you had 193.34.X.88 and 93.209.x.104 - two entirely different subnets. 193.34.X.1 is not a valid gateway for 93.209.x.104, so that machine would have no connectivity. BTW - this isn''t specific to XEN, it''s a general networking/IP addressing issue. I''m still trying to figure out exactly what you are being provided with in terms of IP addresses. Is 193.34.X.88 the only address you have in the 193.34.X.0/25 subnet ? Did your ISP give you a gateway address to use in the 93.209.x.104/25 subnet ? My **guess** is that 193.34.X.88 is your "outside" address, and that your ISP routes the 93.209.x.0/25 addresses to it. If that is case, you need a router between 193.34.X.88 and 93.209.x.0/25. My preference is to use a separate DomU for a two port firewall (see the thread titled "Question about using Xen in a periphery firewall/router" from last week). Alternatively you''ll want to run your Som0 in routed mode with 193.34.X.88 as your outside address, and something in 93.209.x.0/25 for your inside address. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.

Either run Xen in routed mode and connect your Dom0 to the outside network (with a 193.34 address), or run a DomU as a two-port firewall as per the earlier thread I referenced. I would suggest the latter - it''s a lot easier to setup securely (firewalling/iptables can be tricky to get right in Dom0). -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.

I ask for ISP more info at IPs. I get all nessesery info: Addresses: 93.104.X.230-233 Network: 93.104.X.0 Gateway: 93.104.X.1 Broadcast: 93.104.X.255 Netmask: 255.255.255.0 How to setup? simple enable bridge and use these settings to domu ? i can use 93.104.. adress also dom0 if nessesery.
