Hi,
[Please ignore this post... I was confused. A good night sleep and I saw the error of my ways.

I followed this
Howto on how to setup a load balancing.
This is what I am trying to do
Code:
+-------------lb1---------------+ +-----------------XEN----------------------+
+---->| 192.168.1.51 -> 192.168.100.1 |--+ | +---------------------+ |
| | | | | | Dom1 192.168.100.21 | |
| +->| 192.168.0.1 (hb) | | | +---------------------+ |
WAN --> 192.168.1.50(v) | | +-------------------------------+ +-->| 192.168.100.20 |
| +->| 192.168.0.2 (hb) | | | +---------------------+ |
| | | | | | Dom2 192.168.100.22 | |
+---->| 192.168.1.52 -> 192.168.100.2 |--+ | +---------------------+ |
+-------------lb2---------------+ +------------------------------------------+
(v) = IPV
hb = heartbeat
lb1 = load balancer
lb2 = load balancer
I understand that traffic coming from the 'WAN' will point to the IPV 192.168.1.50 so whatever box (lb1 or lb2) hosts the IPV, the traffic will go through it.
What I don't understand is how traffic that is initiated from one of the DomX will know how to reach the WAN and chose between lb1 or lb2?
Do I need to have 2 IPVS? One for
192.168.1.51/52 and one for
192.168.100.1/2?
Code:
+-------------lb1----------------+ +-----------------XEN----------------------+
+---->| 192.168.1.51 -> 192.168.100.11 |--+ | +---------------------+ |
| | | | | | Dom1 192.168.100.21 | |
| +->| 192.168.0.1 (hb) | | | +---------------------+ |
WAN --> 192.168.1.50(v) + | +--------------------------------+ + 192.168.100.10(v) -->| 192.168.100.20 |
| +->| 192.168.0.2 (hb) | | | +---------------------+ |
| | | | | | Dom2 192.168.100.22 | |
+---->| 192.168.1.52 -> 192.168.100.12 |--+ | +---------------------+ |
+-------------lb2----------------+ +------------------------------------------+
Any pointers to documentation that will explain this to me is welcome
Thank you all.
Problem understanding where to set IPVS in load balancing.
