Re: [Xen-users] how to assign public IP for different dom

Within my local lan, I have a Centos box with 6 domU. What I would

in my dom0 and in my local lan router to configure different ip for
each domU?
Sorry, but my crystal ball is on the blink - you'll have to specify
what your problem is !
I can GUESS that your WAN router is doing NAT, and I can GUESS that
you've actually got the public IPs assigned to you by your ISP. There
really is nothing special to Xen here, all you need to do is
configure your network in the same way you would configure a network
of real machines, and configure your WAN router to do the inbound NAT
mapping or routing as appropriate.
One option is to configure your WAN router to route the traffic
without doing NAT - and then configure each machine with a public IP.
If you want the machines to be multihomed (ie have address on the
internal network as well as the public network), then I believe as
recently as this week there have been one or two threads here on how
to configure multiple networks on the Xen host and guests.
Or you can leave the NAT in place, configure each machine with an
RFC1918 private address, and use a static NAT mapping in the router
to forward traffic to the appropriate internal address.
