Local Edit but host as a website?

Hi Everyone,

I am looking for some advice which I ma hoping is a quick and easy fix to an issue which is bugging me !

Basically, I host a blog from my NAS (synology DS209) which works well.
It is available on the web although limited to family members only.

The issue I am trying to resolve, is how can I edit the site locally (so 192.168….) and also maintain the website address. I don’t want to continually have to hack around each time I go from editing.

Advice appreciated !

Thanks
