Port-Mapping

Hi all, sorry for my bad english…
…i’ve a problem with my “Peplink Balance 30” (latest firmware)…
i wanna to redirect all request from any WAN or from Internet to a single IP (es. 10.0.1.10)…and i wanna do it for every port.
There is a function the allow it? And how can i do it?
if i wanna to redirect all port to IP 10.0.1.10 and only one port (for example the port 3000) to IP 10.0.1.11…is it possible?
How can i do it?

Thanx a lot for your assistence…and sorry for my bad-practice

We can use NAT mapping to bind one external IP to one internal IP address. Here is a step-by-step guide.

There is no easy way to forward all ports but one today. But I am really curious of what application we are needing this for?
