This is
not something that we would be willing to do on shared hosting. On the technical side of things, it would require lots of reconfiguration of the server-wide rules in "iptables", which is not something we wish to do. It would require even more reconfiguration since this would have to be setup per-domain, and each shared hosting account is on the same IP address as their free hosting server provides them with. I honestly don't see why you would need to redirect a port - maybe you could clarify what you wish to do - but if you really want to do this, then please take a look at
our VPS services as that gives you full control of a machine in a virtual environment.
Thank you,
