Is it possible to do "double NAT" on pfsense?

Puma

Hello,

CURRENTLY :

We have a customer which has a connection between their premises and ours.

We had set up several years ago:

ROUTING : set up the gateway of their router : 192.168.1.1
CARP Virtual IP : 192.168.1.18
A NAT for their connection where the NATed was in the same IP range as their router, and NAT outbound.

That is, the customer reachs our services by taping the IP for example: 192.168.1.18 and the redirection of the real IP is 172.16.1.15

CHANGES

This customer changes ISP and there is some changes of the previous architecture.
The customer wants to review their addressing plan and the new router is configured with a different IP as before and outside of the existing NAT : 10.23.3.X

We have our existing NAT rules and we would like not to change the existing NAT configuration : 192.168.1.18 and the redirection of the real IP is 172.16.1.15

But we must create another NAT now? If yes, is it possible and how to configure this in pfsense now please ?

Thank you.
