I've to setup a lvs dr setup with 2 windows 2003 webservers (web edition).
It's works fine with a NAT setup, but that isn't what I want.
Now I've added a win2k3 webserver and a linux webserver (for testing).
LVS only connects with the linux servers
and returns a webpage (so this one is working fine), but it never
connects with the windows server.
This is how I configured the windows server:
- I added a local loopback adapter
- Configured it with the vip address (192.168.0.7) and a mask of
255.255.255.255 (through regedit)
- The metric: 254
- Firewall off
- ICS service stopped
- Internal network address configured with ip 192.168.0.8
The loopback is only 10Mbit (don't know if this is right?) and only
reciveice packets and is not sending.
My LVS setup:

Here is my ouput of ipvsadm -L -n:
IP Virtual Server version 1.2.0 (size=4096)

-> 192.168.0.3:80 Route 1 0 0
-> 192.168.0.8:80 Route 0 0 0
It's strange that the weight on the for the linux webserver is 1 and the
windows is 0

I've googled around and read the mini-HOWTO about adding a windows
webserver, but this reference only to NT en win2k.
I also read this PDF file
"http://www.loadbalancer.org/pdffiles/loadbalancersetup.pdf";, but also
didn't help.
The ldirector seems to work fine, but I've know idea what's wrong with
the win2k3 machine.
