If you are using DR-lvs you should rather use the physical interface
where your lvs-machine sends its packets.
Is your lvs-interface in the same subnet as the real-server-address?
Do you have a real interface that is located in the same subnet as the
real-server-address?
Here is what I use for DR on my real-servers (lvs has an own vlan so the
real-server-address is not on the same subnet):
Linux-Kernel-Version is 2.6.18.8,
LVS_IFACE=eth2 # in my case
PROCNET=/proc/sys/net/ipv4/conf
# This prevents other interfaces from answering arp-calls to
REAL_IP
echo 1 > ${PROCNET}/all/arp_filter
for i in ${PROCNET}/eth*
do
echo 1 > $i/arp_filter
echo 1 > $i/arp_ignore
echo 2 > $i/arp_announce
done
# Suppress "martian source" filtering on LVS_IFACE
sysctl -q -w net.ipv4.conf.default.rp_filter=0
sysctl -q -w net.ipv4.conf.${LVS_IFACE}.rp_filter=0
# Add REAL_IP so that the local service can listen to it
ip addr add ${REAL_IP}/32 dev ${LVS_IFACE} scope link >/dev/null
2>&1
This setup does NOT need ip-forwarding.
