Hey everyone! I'm working on a basic cluster setup using Calico with PureLB. Everything is functioning well in terms of requests being answered correctly by the LoadBalancer. However, I want the same ports used in my LoadBalancer (specifically the nginx ingress) to also respond directly on the host interface, but I haven't had any luck so far.
I've tried creating a GlobalNetworkPolicy and a HostEndpoint as you can see in my YAML specs, and I've also set my nginx-ingress LoadBalancer's externalTrafficPolicy to Local, but something still seems off. Is this actually possible? What am I missing here?
Thanks in advance for any clarity you can provide!

Have you made sure that the host endpoint is enabled? That could be a crucial step. It might help to check out this tutorial for some guidance on Calico with eBPF and XDP: tigera.io tutorials. That could clarify a few things for you!
That tutorial requires an account, but I'll check it out on my computer later. My Calico setup is already in eBPF mode without KubeRouter or Kube Proxy. I have the helm chart values for the Tigera operator as well, so I'll share that too. Just confirming, is the eBPF config I have enough? How would I go about checking if eBPF is properly configured?
