Technical Details

what runs on :6706

ForCES (Forwarding and Control Element Separation) carries control-plane protocol messages between a CE and an FE. SCTP provides the transport on port 6706; SCTP preserves message boundaries, and the payload uses ForCES protocol framing, including its common header and structured message data. The port identifies the low-priority channel; it is not a general-purpose service, and an SCTP listener alone does not establish that the peer is a valid ForCES element.

security overview

ForCES is a network-control protocol, so an unintended or untrusted peer could pose a risk to forwarding behavior. Keep this port on a trusted control network rather than exposing it to the internet; SCTP does not encrypt traffic by default, so deployments should use appropriate network isolation or separate security protection. The assignment is obscure and has not been observed open in the cited scan data.
