How to set source interface/source ip with node-ipc?

I would like to use another network interface for a socket client using node-ipc on Linux (RH, CentOS).

I tried:

ipc.config.interfaces = {
    localAddress: true,
    localPort: false,
    family: false,
    hints: false,
    lookup: false
};

and

ipc.config.interfaces = {
    localAddress: '1.2.3.4',
    localPort: false,
    family: false,
    hints: false,
    lookup: false
};

without success. I can see with wireshark the source IP is not 1.2.3.4.

How can I set the source IP in a code using node-ipc ?

I couldn't find any example...
