In modern telecommunications architectures, particularly 5G Core networks (such as deployments using open-source projects like free5GC), SCTP is a foundational and mandatory transport protocol. It is required for the N2 interface to handle NGAP signaling between the RAN (gNB) and the AMF.
Currently, the ziti-tunnel-sdk-c only intercepts and tunnels TCP and UDP traffic. When we attempt to extend OpenZiti's zero-trust overlay directly to these critical telecom signaling interfaces, we are completely blocked because the tunneler drops or ignores SCTP packets. This limitation prevents us from bringing zero-trust networking to the 5G control plane natively.
I hope native support for SCTP interception and tunneling can be added to the SDK, so that SCTP traffic can be seamlessly intercepted at the TUN interface and routed through the Ziti network alongside standard TCP and UDP traffic.
Thank you for your time and consideration!
