Thank you! I just can't understand what I'm doing wrong here then - I
am only getting one actual IP, whatever I'm putting in. I stopped FW2
to make sure I have a coherent setup.

crm(live)# configure show
node FW1
node FW2
primitive ClusterIP.144.1 ocf:heartbeat:IPaddr2 \
        params ip="10.144.1.1" cidr_netmask="32" clusterip_hash="sourceip" \
        op monitor interval="120s"
clone CloneIP ClusterIP.144.1 \

Is this NOT what I should have configured?
