i am using this with haproxy

listen FTP :21, :10000-10250
    mode tcp
    server ftp01 realserverip:21 check port 21

No, this is not possible. Haproxy does not understand the FTP protocol, and therefore can't do things like re-write the FTP commands and responses that include the true IP address of the FTP server.

If that's a requirement, then you'll have to find a different proxy solution.

NGINX Reverse Proxy – URL Rewrite

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.

HAProxy HTTP vs TCP – Key Differences and Use Cases

By using the HTTP method in the HAProxy config, you have access to several HTTP-specific options. For example, you can choose different backends based on the URL in the HTTP request. When specifying TCP mode, HAProxy does not evaluate the HTTP headers in the packet.

So, you can definitely just use TCP for HTTP traffic, but you wouldn't have the additional HTTP options. As a side note, unless you're using the SSL features, you have to use TCP for HTTPS traffic because the packets are encrypted and HAProxy can't view the HTTP headers.
