Accessing database via local network and Resolve Mission Control at the same time..?

I've been using a shared database for 3+ years at my office.
Thanks to all the instruction on YouTube and web articles like this one from mixing light.

Recently, I've been trying to access it from remote location or want freelance editors to access the database via internet. I found this amazing app on YouTube and made it work perfectly. The problem is I can access the database remotely via fireguard but not be able to access it locally like previous method.
My goal is to access it remotely and locally at same time. I see some methods like creating database on AWS, but I'd like to have somewhat stable access when accessing from local network.

Do you guys have any suggestions..?

best,
