Multiple Wan subnets on SRX550 in HA

Hi

I need help with correct assign new WAN IP pool to our SRX550 in HA 

1. old pool 

xx.xxx.232.136-139

2. new pool

xx.xxx.239.17-29

Actual configuration:

WAN interface

reth0 {
        description "LINK TO INET";
        redundant-ether-options {
            redundancy-group 1;
        }
        unit 0 {
            family inet {
                sampling {
                    input;
                    output;
                }
                address xx.xxx.232.136/23;
                address xx.xxx.232.137/23;
                address xx.xxx.232.138/23;
                address xx.xxx.232.139/23;
            }
        }
    }

Static route

route 0.0.0.0/0 next-hop xx.xxx.232.1;

In actual setup we use new pool in SNAT and DNAT, accessibility from internet isnt problem. But IPs dont see each other.  New pool is statically routed from ISP to xx.xxx.232.136 

ping from oldpool IP to oldpool IP = no problem

ping from oldpool IP to newpool IP = problem

ping from newpol IP to newpool IP = problem (from VM under NAT, SRX ping: bind: Can't assign requested address)

ping from internet to newpool IP = no problem

Any advice ?

Thanks
