Firewall whitelist rule/s for Teams custom app bot

I have a custom app that implements a bot in Teams, the bot url points to a server hosted within my local network. All works fine when my firewall is turned off. So my question is - what ip address ...

Microsoft does not provide a single static IP for Teams bot. For development, you can use ngrok to tunnel your local bot to a public HTTPS endpoint, which avoids firewall issues. For production, deploy your bot to Azure or another public cloud.

Thanks, those may be options to explore. I was hoping to get some IP list to whitelist because no matter where the endpoint is hosted, it may still be secured behind a firewall.
