the host service providers route the public ip 74.*.64.64/26

I searched the internet,and found
this:http://www.debian-administration.org/articles/360.I trid as the
article said but fail.
I think I should setup the gateway first,which will be best
choice,virtual host or physical host? can do you have examples,no
mater NAT or BridgeÅB
Since you have multiple public IP's, I would use
them for any public facing services - so don't
use NAT. If you want an 'internal' network with
more devices, then have this separately (and use
NAT for that).
I would use a routed setup - your outside
interface will have address 74.*.64.18, and your
inside interface will have 74.*.64.nn where nn is
any of your usable IPs (personally I would
configure it as 74.*.64.65/26.
I personally would run a dedicated system (either
a small 'real' box, or a VM guest) just to run
the router, and I would install a firewall on it
(my preference being Shorewall
http://www.shorewall.net). Make all internet
access go through this dedicated box.
You can either 'hide' the external interface and
make it available directly to your guest (which
is what I have at home), or have a separate xen
bridge with the external interface in it (and not
made available to any other guests).
If you want a 'private' internal network, then I
would suggest a 3-port firewall setup with
external, dmz, and internal interfaces - and have
xen bridges for dmz and internal (plus external
if you do it that way) networks.
