Assume I have a 172.16.0.0/16 network, it is then Nated to a 192.168.1.0/24 network.
This 192.168.1.0/24 is then NAT via a firewall to a public ip so that there is internet access.
So being a routing issue, how can I route to the 172.16.0.0/16 network.
After vpn into firewall, I can only reach the 192.168.1.0/24 but not the 172.16.0.0/16

You can do one of the following:

Hi,
Please do me a favour and give me some commands for 2nd or 3rd for better illustration.

Hello
The rtr that is natting 172.16.0.0/16 towards the Fw is the key it will need to be dynamic host to host NAT for connection to be successful
Alternatively you could just have a static route from the FW towards that rtr for 172.16.0.0/16 subnet and perform nat on the Fw for it thus removing NAT from the rtr.

public NATing and dual NAT in same FW ?
If yes that not work.
The FW do only one NATing for traffic here it do NATing to 192.168.1.0 or 192.168.1.0 to public not both.

you can make 172.16.0.0 NAT to 192.168.1.0 only if traffic go via VPN or other
and NATing to public if traffic have destination any
