SCTP support (beta)

Note

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

Enabling

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

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

• KPR

• BPF masquerading

• Egress gateway
