Use fwmarks.
Have an iptables rule (in the 'mangle' table, IIRC) to match on the /23:
iptables -t mangle -A PREROUTING -d 192.168.0.0/16 -p tcp \
-m tcp --dport 80 -j MARK --set-mark 0x1
Then in the IPVS config (however you configure it) match on the mark
value rather than a network prefix.
For keepalived, for example:
# Simple only-local fwmark config
virtual_server fwmark 1 {
delay_loop 10
lb_algo rr
lb_kind DR
persistence_timeout 60
protocol TCP
real_server 127.0.0.1 80 {
weight 100
TCP_CHECK {
connect_port 80
connect_timeout 5
}
}
}
Simples!
