route internal subnet using non primary WAN IP address

Hi guys

Im trying to send traffic from an internal subnet to use the non primary ip address (222.333.19.65) as the public ip

show interfaces pp0 unit 0
...
family inet {
        address 222.111.19.62/32 {
            destination 222.111.19.61;
            primary;
        }
        address 222.333.19.65/28;
        address 222.333.19.66/28;
        address 222.333.19.67/28;
        ...
    }

Currently all traffic on 192.168.1.0/24 is routed out using the default route which shows 222.111.19.62 as the public ip

route 0.0.0.0/0 next-hop pp0.0;

I would like to route the internal subnet 192.168.2.0/24 to use the 222.333.19.65 IP address publicly. Can you suggest how i would do this?
