UDP Relay 一直没成功

[soffchen]

base {
        log_debug = off;
        log_info = off;
        log = "file:/var/log/redsocks.log";
        daemon = on;
        redirector = iptables;
}

redudp {
        local_ip = 127.0.0.1;
        local_port = 1053;
        ip = 127.0.0.1;
        port = 19443;
        type = socks5;
        dest_ip = 8.8.8.8;
        dest_port = 53;
        udp_timeout = 3;
}

使用gost -L=:19443的时候，成功解析了

使用gost -L=:19443 -F=socks+wss://ip:port或者gost -L=:19443 -F=socks://ip:port后

我也碰到同样问题，UDP转发一直不成功，不管用啥协议组合，日志如下

今天又试了一下，IPv6同样也不支持UDP转发，socks5协议，其他协议和组合协议一样不能，日志如下
