Advice on Staging System Setup

Hi Wapplers,
I am hoping someone can point me in the right direction.
I have a local development docker engine target (NodeJS) running Wappler on my Mac.
I have a remote Production docker engine target (NodeJS) running in a Digital Ocean Droplet.

This is working nicely. However…

I have on my same LAN another Mac that I want to use a Staging/Development mirror environment, this doesn’t have Wappler, but does have Docker. I can open up my router firewall to allow external access to this IP for testing.

Can someone help with the best way I can configure this.
I cannot work out how to do this in Wappler Target config. Is this setup possible?

Thanks in advance.
