[Xen-users] NAT various domUs to multiple IPs on one NIC

[revEn <reven@xxxxxxxxxxxx>]

Hi, I'm new to Xen and have no idea how to make this works...

Here is my situation:
                     
                                                                        
           inet
                                
|-----------------------------------|-----------------------------|
                      dom0 - eth0                                   
dom0 - eth0:0                     dom0 - eth0:x
                      A.B.194.16                                     
A.B.194.17                           A.B.C.D
                               |                                       
              |                                          |
      |----------------|---------------|                     
|-------------|                     |-------------|
domU1              domU2            domU3           domU4         
domU5         domUx         domUy
10.0.0.1            10.0.0.2           10.0.0.3         10.0.1.1        
10.0.1.2       10.0.x.y        10.0.x.y
Ok, i have only one NIC ( only one port in switch is possible ) and some 
public IP's and what i want is the 10.0.0.0/24 is NATed through 
A.B.194.16, 10.0.1.0/24 is NATed through A.B.194.17 etc.
Reason for this is so in every group of domUs / non-public nets is for 
example apache with sll and some other apps what needs 1 public IP and 
need to be separated from another group of domUs, where is for example 
testing apps / game servers etc. what needs another 1 public IP AND 
another CPU prio, etc.
I read many threads in this ML and spend x hours on google and still 
dunno how to realise this :(
Thanks for any help in solving this problem.

With regards, Tomas Wodecky aka revEn
