I have a docker container that runs a web app. The webapp needs to connect to a test database inside my companies VPN. I need to be able to access this webapp from the public internet.

When I am disconnected from our VPN I can hit the webapp without issue using my public IP assigned by my ISP. Its the IP for my router and I have port forwarding enabled and firewall opened correctly. However its not able to connect to the database.

When I start the VPN the app is able to connect to the database and I can open the pages from the host inside the VPN. However I can no longer access the webapp from the public internet.

Is there some way to allow these connections to come in even while connected to the VPN?

I assume this is a fairly standard use case. In reality I'm oversimplifying and my webapp has dependencies on a slew of services only accessible inside the VPN. I could try to dockerize everything but it would be a pretty massive undertaking. The app needs to be accessible to the public internet because of integrations with 3rd party apps sending webhooks and making API calls back to the webapp.
