[users@httpd] port redirecting mapping

[varun]

Is it possible to redirect a request for one port to another one.
Say a request like *http://domain_name:3030* be accepted and
redirected/mapped, so that the server should be able to process the
request like*http://domain_name:3000*. And a direct request like 
*http://domain_name:3000*
should be restricted.
Is there any modules, directive in apache. I am new to apache. On Ubuntu 
12.04.
