Re: [Xen-users] Help me to set up network (routes)

But, my IPS give me just ONE IP - 10.9.3.92. I can't use any other address. I'm afraid that my configuration will invoke an "IP address conflict". And, in either case, if I would like to connect to 10.9.3.93 from my Dom0? Where it will connect? to DomU or to real user of my ISP?

So, after 2 days of bridging magic, I decide to drop that idea and now looking for another solution.

I would seriously consider running a DomU dedicated as your outside router/firewall. I do that, in my case I use a Netgear DM111P ADSL-Ethernet modem and an ethernet card in the server. I use pciback.hide to hide the ethernet card from Dom0 and assign it to the router DomU (which runs Shorewall). IMO this gives you an easy to configure and easy to secure setup - your 'router' is a simple "two ethernet card" job, and Dom0 is not directly connected to the outside world.

As you've found out, the networking in Dom0 is non-trivial, and it's a lot easier to separate out the external routing/firewall functions into their own DomU.

However, I don't know what is required to use your outside interface in a DomU - all I can see is that it's a PPP interface, so is that using an ADSL modem card ?
