Static NAT before VPN tunneling

Hello, I would to create a configuration where hosts belonging to LAN network will be translated via static nat before the VPN tunnelling.IS this configuration supported by Mango or Brume 2 platform?
LAN network\24

SNAT: → →

TUNNELING via IPSEC VPN to remote site

Mango or Brume doesn’t support IPSEC.
Could you draw the topology for a better understanding of your requirement?
