|
|
|
|
#### udp_over_stream
|
|
|
|
|
|
|
|
|
|
This is the TUIC port of the [UDP over TCP protocol](/configuration/shared/udp-over-tcp), designed to provide a QUIC
|
|
|
|
|
stream based UDP relay mode that TUIC does not provide. Since it is an add-on protocol, you will need to use sing-box or
|
|
|
|
|
another program compatible with the protocol as a server.
|
|
|
|
|
|
|
|
|
|
This mode has no positive effect in a proper UDP proxy scenario and should only be applied to relay streaming UDP
|
|
|
|
|
traffic (basically QUIC streams).
