SCTP support (beta)


This is a beta feature. Please provide feedback and file a GitHub issue if you experience any problems.


Pass --set sctp.enabled=true to helm.


You can also watch a video explanation of Cilium’s SCTP support in eCHO episode 78: Stream Control Transmission Protocol (SCTP).


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 [*]


[*] 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.


Cilium does not support the following for SCTP:
  • Multihoming

  • Policies for pod-to-VIP

  • KPR

  • BPF masquerading

  • Egress gateway
