Hi all, is there any reason why we would do this ? instead of direct port to port mappings ?

Maybe for security or some kind of restriction/limitation on an application. i.e map port 80 to 81 for outside so your web site wouldn't be as easily accessible...although a fairly simple scan would still detect it.
Maybe someone else has some better reasons. :)

We had to do this based on security based on obscurity.
If we change the port then people will not access it, which is stupid logic. We had changed all common ports on some common applications based on development needs. Instead of actually having a security team who knows what to do.

you do this for several reasons:
1- you have limited public IP addresses. For
example, for home users, you normally have
only 1 public IP address. In order to access
hosts behind the firewall, you have to resort
to port-redirect. Either that or SSL vpn or
IPSec VPN.
2- people just wants to learn it,
