<vip.ip.address> = "1.2.3.4" for this example
<RIP.ip.address> = "4.5.6.7" for this example
On the DIP, first load the ipip.ko kernel module (ensure your kernel
supports tunneled interfaces.
/sbin/ifconfig tunl0 1.2.3.4 netmask 255.255.255.255 up
/sbin/ipvsadm -A -t 1.2.3.4:80 -s rr
/sbin/ipvsadm -a -t 1.2.3.4:80 -r 4.5.6.7:80 -i -w 1 (here the port
designation :80 on the RIP is not really needed, and -i specifies to use the
tunneling method)
On the RIP, load the ipip.ko kernel module; then
/sbin/ifconfig tunl0 1.2.3.4 netmask 255.255.255.255 up
didn't even need to restart apache. it just worked at this point.
It's the very basic LVS-tun solution.
Bill, what iptables rules did you use to get your solution working?
Hope this helps...

Hi Philip
I'm using the following on all of my real servers:
iptables -t nat -A PREROUTING -d $VIP -p tcp --dport 0:65535 -j REDIRECT
echo 1 > /proc/sys/net/ipv4/ip_forward
I would like to figure out a way to get around the need of having to
do anything at all on the reals, much like the way Netscallers behave.
But essentially, our setups are very similar.
