Did I understand it correctly?

If I want someone else to have an IPsec tunnel into my pfSense I can give them whatever subnet address they want, for instance 10.10.10.0/24, if I use binary 1:1 NAT?

Does that also mean that I can have several IPsec tunnels using the same subnet address, for instance 10.10.10.0/24 that I will NAT into other real IP addresses?

Example:
Link 1: IPsec tunnel connects to 10.10.10.0/24 but real IPs are 192.168.1.0/24.
Link 2: IPsec tunnel connects to 10.10.10.0/24 but real IPs are 192.168.2.0/24.

Thanks in advance!
