Technical Details

what runs on :6068

TCP port 6068 is assigned for GSMP/ANCP. ANCP is based on GSMPv3 and runs as a TCP session between an access node and a NAS; messages use GSMP-style headers and length-based framing over the TCP stream. It is used in provider access networks to exchange control and operational information, rather than for ordinary client traffic. Deployments commonly keep the session within the operator's control network.

security overview

ANCP can carry messages that affect access-node behavior and subscriber services, so an exposed listener could present a control-plane risk. It is not encrypted by default; restrict it to trusted network paths and protect it with network-layer security such as IPsec where appropriate. It should not be exposed to the public internet.
