Hello!
I need to do a work of university and I'm interested to use LVS, but I have a problem that I can't solve. I would appreciate it could only help.

I have some virtual machines (virtualbox) of Ubuntu running in my Windows Vista. These machines have connectivity between them. The problem: for the load balancing and high availability I use ipsadm + keepalived, and it works only if the load-balancer is the same machine that the client. If the machines are different it is'nt work.

I tried many things (for example use ip private in the load-balancer instead a public ip) and I searched information on the web.

The script that I use in the balancer is:

Code:
#!/bin/sh 
 
modprobe iptable_nat 
 
echo 1 > /proc/sys/net/ipv4/ip_forward 
 
IPTABLES=/sbin/iptables 
 
REDLOCAL=192.168.1.0/25 
 
$IPTABLES -F 
 
$IPTABLES -t nat -A POSTROUTING -s $REDLOCAL -j MASQUERADE 
 
$IPTABLES -A FORWARD -s $REDLOCAL -j ACCEPT 
 
IPVSADM=/sbin/ipvsadm 
 
$IPVSADM -C 
 
ipvsadm -A -t 10.0.2.15:80 -s rr -p 
 
ipvsadm -a -t 10.0.2.15:80 -r 192.168.1.35:80 -m 
 
ipvsadm -a -t 10.0.2.15:80 -r 192.168.1.36:80 -m 
 
keepalived start
And in the real servers I only change the default route to point to the balancer's addres:
Code:
route add default gw 192.168.1.34
Thank you very much and sorry for my bad English.
