We just migrate 1.7.17 to 2.1.3 in a k8s cluster.
Metallb is providing the external IP, ingres configured in the app namespace, traefik and services configuration
Metallb is still providing external IP, no more ingress, we use Kubernetes CRD, and traefik configuration in the app namespace.
The thing is that now we can't reach traefik from the oustide. If we are in the LAN of the external IP it works, but outside we see a connection and then a connection close.
Any idea ?
