SRX100 virtual instances routing to "wan"

Hello,

Ive set up 3 virtual instances on a SRX running ospf between them and it works fine. I have 1 instance with physical interface which connects to another router for wan access. (fe-0/0/0 has IP from 192.168.0.0/24 SN)

I can ping 8.8.8.8 from routing-inst1 which has interface on it.

Ive then added static route 0.0.0.0/0 next hop 192.168.0.1 and propagate it to OSPF

I can ping ospf links between routers but I cannot ping 8.8.8.8 from routing-inst2 or 3.

Im using SRX in packet  forward mode.

So what Im trying to achieve is that I can ping WAN from any route instance. There must be something Im missing.

Below is my config

interfaces {
    fe-0/0/0 {
        unit 0 {
            description p2p-to-upstream;
            family inet {
                address 192.168.0.100/24;
            }
        }
    }
