SNAT node to VIP iRule

Hey everyone -

• V13
• All nodes point to F5 as default gateway
• Forwarding IP VIP 0.0.0.0

We would like outbound connections from each node to SNAT to it's respective VIP IP. Does someone have a configuration/iRule that will work for this? Also, if there was a way to use the same iRule for each VIP (without IP changes), that would be ideal.

So based on configuration below, how can node1 (10.4.55.10) SNAT from existing VIP (10.3.0.10) ?

ltm virtual VIP1 {
    destination 10.3.0.10:5986
    ip-protocol tcp
    mask 255.255.255.255
    pool POOL1
    profiles {
        tcp { }
    }
    source 0.0.0.0/0
    translate-address enabled
    translate-port enabled
}

ltm pool POOL1 {
    members {
        NODE1:5986 {
            address 10.4.55.10
            session monitor-enabled
            state up
        }
    }
    monitor tcp_half_open 
}

ltm virtual vs_0.0.0.0_any {
    destination 0.0.0.0:any
    ip-forward
    mask any
    profiles {
        fastL4 { }
    }
    source 0.0.0.0/0
    translate-address disabled
    translate-port disabled
}

net route external_default_gateway {
    gw 10.3.0.1
    network default
}

net self FLOATING_IP {
    address 10.4.55.1/24
    allow-service all
    floating enabled
    traffic-group traffic-group-1
    unit 1
    vlan NODE1_VLAN
}
