KCPTUN for data diode?

[samwell-ho]

As far as I know, KCP transmits data based on UDP. UDP can be used in one-way data transmission solutions (data diode).

Can I try kcptun for data diode case? Meaning only UDP packets go from client to server but not from server to client?

well, why not just drop all the incoming data on server side, like using iptables?

The question was: is KCP one-way or does it require confirmation of packet transmission between the client and the server??

It needs ACK confirmations of course. It's a reliable transport protocol.
