k8s: NodePort implementation incomplete #242

Open lorenz opened 1 year ago

lorenz commented 1 year ago

nfproxy doesn't fully implement NodePort-specific behavior. Missing are:

Handling externalTrafficPolicy=Local
SNATing all traffic without externalTrafficPolicy=Local (otherwise we do DSR which doesn't work on a lot of systems)

We need to implement this to make NodePort work properly.

https://review.monogon.dev/c/monogon/+/1924 fixes NodePort with externalTrafficPolicy: Cluster. externalTrafficPolicy: Local is not implemented in nfproxy as far as I can see and will need to wait until we do more load balancer work.
