I used to use a single docker image with a VPN Client (xl2tp) and a mqtt-Server and an Apache. So it was possible to access these two ports through the VPN. Important: The services may only be accessible in the VPN, not from the computer running Docker. A single container is ugly, but it worked.
Now more services/ports should be added. That’s why I want to use individual containers and docker-compose.
version: '3.7' services: httpd: build: dockerfile: Dockerfile context: ./httpd ports: - "80:80" depends_on: - l2tp networks: - hamnet hivemq: build: dockerfile: Dockerfile context: ./hivemq ports: - "1833:1833" - "8000:8000" depends_on: - l2tp networks: - hamnet l2tp: cap_add: - NET_ADMIN build: dockerfile: Dockerfile context: ./l2tp privileged: true networks: - hamnet networks: hamnet: name: hamnet external: true
The whole thing comes up. The VPN IP can be pinged, the ports are accessable from inside the containers, but the ports (http, mqtt etc) are not reachable via the VPN.
What do I have to do to bring http and mqtt into the VPN?
Grateful for hints
