Hi,
Just a note to say that I revisited trying to get VS-DR working today, and
dug out the note Ratz <ratz@xxxxxx> (Roberto Nibali) posted to the list
some time ago:

When I'd been trying it last time, I knew I'd probably missed something
very simple and stupid and I had.
And realised this time what I had done wrong - I'd rather stupidly
forgotten to switch IP forwarding on on the director. (Since we're using
tunneling for the other servers this hadn't affected the Linux boxes...)
In case it's of use to anyone else, to use FreeBSD boxen as real servers:
On the director:
Configure as normal - eg:
ifconfig $ETHER_DEV $VIP netmask 255.255.255.255 broadcast $VIP up
route add -host $VIP dev eth0:0
*Remember* to switch on IP forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward
Add the real server in:
ipvsadm -a -t $VIP -r $FREEBSDBOXIP -g
On $FREEBSDBOXIP,
ifconfig lo0 alias $VIP netmask 0xffffffff up -arp
And as Ratz said, this works absolutely perfectly - many thanks :-)))
Tested on FreeBSD 3.2-STABLE & 2.2.5-STABLE.
Michael.
