Limitations

Cilium supports basic SCTP support. Specifically, the following is supported:

• Pod <-> Pod communication
• Pod <-> Service communication [*]
• Pod <-> Pod communication with network policies applied to SCTP traffic [*]

.. note:: [*] SCTP support does not support rewriting ports for SCTP packets. This means that when defining services, the targetPort MUST equal the port, otherwise the packet will be dropped.

.. warning:: Cilium does not support the following for SCTP: - Multihoming - Policies for pod-to-VIP - :ref:Kube-proxy replacement (KPR)<kubeproxy-free> when port rewriting is necessary: for example, NodePort Services are not supported with the combination of KPR and SCTP.
- BPF masquerading - Egress gateway
