V2ray-core: Support UDP NAT type 2 in dokodemo-door
So far it is type 4 (symmetric) due to some internal designs.
It requires fundamental changes to both internal data structure and VMess protocol to support type 2.

Since we needs to change VMess protocol to support type 2, why not consider to also amend vmess so that udp traffic can be transferred with udp and decrease delay.

No. VMess is designed to be TCP only. If you need a protocol for UDP transfer, we can design another protocol.

OK, I suppose you mean vmess is based on stream transport.

希望v2ray的vmess能支持UDP转发。
I hope vmess can support UDP traffic.

但是我这边用supersocks5却不行，提示UDP被封锁，同等情况下ssr和ss就不会。（服务器和客户端配置已经开启UDP）
