Dears,
Could Nginx stream support FTP PASSIVE?

#er nobody;
worker_processes 4;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

stream
{
upstream port21
{
server 10.122.x.x:21 weight=1;
server 10.122.x.xx:21 weight=1;
}
server
{ listen 21;
proxy_connect_timeout 60;
proxy_pass port21;
}
}

Passive ports are dynamically allocated, so FTP with the stream module
