Unanswered Question

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

I have this problem too.

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


2- people just wants to learn it,
