I'm trying to setup an FTP subdomain, such that all incoming SFTP requests to (say) ftp.myname.com, get routed to a particular internal server, (say) 10.123.456 via port 22. How do I use nginx to route this traffic? I've already setup the SFTP server, and can SFTP directly to the server, say: sftp [email protected], which works fine. The problem is that when I setup nginx to route all traffic to ftp.myname.com, it connects, but the passwords get rejected. I have no problems routing web traffic to my other subdomains, say dev.myname.com (with passwords), but it doesn't work for the SFTP traffic: server {
    listen 22;
    server_name ftp.myname.com;
    return .............
}
 How do I define the return sting to route the traffic with the passwords?  The connection is SFTP (via port 22). Thanks
