There was a problem hiding this comment.
That must have been a pain to debug...
Couple questions below to understand.

In v1.18 Cilium moves to utilizing VXLAN-in-ESP traffic by default. This means traffic between nodes is now ESP and no longer VXLAN when IPsec is enabled. GKE, by default, does not allow ESP traffic between GKE nodes. Therefore, create a ESP allow firewall rule which targets just the cluster nodes.

In v1.18 Cilium moves to utilizing VXLAN-in-ESP traffic by default.
This means traffic between nodes is now ESP and no longer VXLAN when IPsec is enabled.
GKE, by default, does not allow ESP traffic between GKE nodes.
Therefore, create a ESP allow firewall rule which targets just the cluster nodes.
