Technical Details

what runs on :29169

The IANA assignment is for HNBAP and RUA's common association over SCTP on port 29169. The HNB establishes an SCTP association toward the HNB gateway; SCTP provides reliable, message-oriented transport, and the protocols exchange ASN.1-encoded signaling messages. HNBAP handles procedures such as HNB registration, while RUA adapts RANAP signaling for the Iuh interface. SCTP itself does not encrypt traffic; deployments commonly protect HNB connectivity with IPsec through a security gateway.

security overview

This is cellular access-network control signaling, not a service intended for arbitrary Internet clients. Exposing it publicly can invite SCTP probing and attempts to interact with HNB registration or RAN signaling; restrict access to trusted network paths and use the operator's IPsec and gateway controls. SCTP does not provide confidentiality by itself.
