Currently I use FRP to create a tunnel into my network to expose service.
How i'm setup:
AWS Light sail running FRP Server
Server Running the FRP Client
Docker Container
Can Traefik still create that tunnel or does this replace it all together and I expose traefick to the internet? I'm not fully clear on this and any insight would be amazing. Thank you for your time in advance.
I‘m not fully clear what "FRP" is 
Is the "tunnel" a VPN connection?
I encountered a similar problem. I ran frps and nginx proxy manager on a server with a public IP. I ran frpc and traefik on a local virtual machine without a public IP. It seems that it cannot run normally. What's wrong? Ideas?
What does that mean? What do you want to achieve? What does not work? What errors do you see?
