External access to dependent container

[sam-semillia]

Hi,

I want to run NordLynx VPN container, together with another container (OSCAM) to tunnel all OSCAM traffic through NordVpn.
OSCAM should also be availaible from external access as well. Unfortunately external access only works sometimes, most of the time it does not. Internal connections work perfectly fine. The port is forwarded in the router. This is running on docker ubuntu x64.

Can someone help me please?

Thanks, BR

No ideas?
Thanks, BR

This has been frustrating for me too. From host network no problem, from external ip no dice.

Well, I got it figured out. You need to add a forwarding proxy that is not in the same network namespace as the VPN to your docker-compose file and you set it to forward to the app that runs in the VPN namespace.

@Gunther-Schulz I know this post is old, but I'm trying to accomplish the exact same thing and having a hell of a time.

Assuming you're still using this setup, could you share your docker-compose? If not, could you share what you're using now? Thanks!
