OpenVpn nat 1:1 virtual ip to lan ip

[vacant309]

Hi everyone, I have a problem with the nat 1: 1

Wan ip: 90.80.90.100
LAN ip: 172.16.25.10
Openvpn virtualp subent 10.0.30.0/24

considered as needing to transform the ip that enters with openvpn (Example 10.20.30.2) in IP of the LAN subnet (example 172.16.25.2) then out a NAT 1:1

Thanks
