Trident firewall ports

izzi — Wed, 04 Jun 2025 10:17:27 GMT

I have a customer who has been running Trident successfully for a while now, and is standing up a new vServer for Trident access from a separate network with a firewall in between the vServer and the Kubernetes cluster. Which ports are needed for all of this to work correctly? It's an NFS server. I can't seem to find it in the docs.

Communication for Trident -> Storage is over port 443 for management traffic.

NFS traffic from NetApp is the same as NFS traffic anywhere, port 2049. Though there are a few other ports you may need to open to get NFS to fully work.
