Technical Details

what runs on :6080

IANA assigns UDP 6080 to GUE, specified in RFC 8086. It is connectionless: there is no handshake, and each UDP datagram contains a GUE header identifying the encapsulated protocol, with optional extensions or control information, followed by the packet payload. GUE supports carrying network-layer packets through UDP, which can work across routed networks and with ECMP. The port is a convention for GUE tunnel traffic, not a guarantee that every listener on UDP 6080 speaks GUE.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

GUE does not provide encryption or peer authentication itself. An exposed tunnel endpoint may accept spoofed or unauthorized encapsulated packets, potentially allowing traffic injection or abuse of the network behind it. Restrict access to trusted tunnel peers and apply source validation and filtering; a GUE endpoint generally should not be exposed broadly to the internet.

Record

iana registry entry

port: :6080
service: Generic UDP Encapsulation (GUE)
transport: UDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services
usage: GUE is a standardized tunnel encapsulation, not a conventional application service. Network and overlay tunnel endpoints may use UDP 6080 to carry IP or other protocol packets; it is uncommon on the public internet, so an open port is likely a deliberate tunnel endpoint.
