 Requires that application protocol does not depend on udp payload size.

 QUIC initial packets are recognized. Decryption and hostname extraction is supported so `--hostlist` parameter will work.
-Wireguard handshake initiation, DHT, STUN and [Discord Voice IP Discovery](https://discord.com/developers/docs/topics/voice-connections#ip-discovery) packets are also recognized.
+Wireguard handshake initiation and DHT packets are also recognized.
 For other protocols desync use `--dpi-desync-any-protocol`.

 Conntrack supports udp. `--dpi-desync-cutoff` will work. UDP conntrack timeout can be set in the 4th parameter of `--ctrack-timeouts`.

 можно изменить 4-м параметром в `--ctrack-timeouts`.
