How to make other devices in the same network see my VM?

So I have a VM with IP 172.16.xxx.xx. Network setting is "Share with my Mac".

My host (mac) can see the VM (ubuntu), and VM is able to connect to the internet.

But my phone in the same network (via wifi), is not able to connect to this VM.

Any idea how to make it see the VM?

I have tried setting adapter to use Wi-Fi under bridge networking, but ubuntu doesn't seem to be able to configure for it?

Update:

So I found out that it has something to do with the router's settings.

I tried setting up a new VM with Wifi as Bridge and it works with my home network.

Any idea how I can configure the office's router so that the WiFi bridge networking will work?
