Try to add layer4 information ( port numbers ) to set of inputs for IP2 
hashing function . It should help , since
at least clients shall use different tcp/udp ports numbers from ephemeral 
range

bubu at lab-m5-2# show forwarding-options
hash-key {
    family inet {
        layer-3;
        layer-4;
    }
}
