Tunneling (Dev Tunnel)
If you're running the Bot Framework Emulator behind a firewall or other network boundary and want to connect to a bot hosted remotely, you will need to install and configure tunneling software.
Computers running behind firewalls and home routers are not able to accept ad-hoc incoming requests from the outside world. Tunneling software provides a way around this by creating a bridge from outside the firewall to your local machine. Dev Tunnels is an example of such tunneling software.
- Download the Dev Tunnels in your OS
- Create a tunnel pointing to your local port, eg:
devtunnel host -a -p 3978 - Configure the dev tunnel URL in Settings
