      Good Morning.

      I'm having some difficulties in redirecting ips through vpn with NAT.
      I have the following configuration:
      Fortigate: Subnet 192.168.2.0/23
      pfSense: Subnet 192.168.3.0/24

      I configured the IPSEC VPN between the two firewalls like this:
      Fortigate: I created a range of virtual ip 10.10.2.0/24

      In VPN it was as follows phase 2:

      In pfsense vpn was as follows phase 2:

      both ends closed...

      So far so good, but I'm having trouble routing ips, for example:

      In the fortigate that is in the matrix we have a VPN with one of our clients that is configured with a nat and we call the address 100.100.0.3/24 (webservice) that is working.
      I made a rule in fortigate to redirect 100.100.0.3/24 to virtual ip 10.10.2.3/24.

      In the branch I try to call the ip 10.10.2.3 but I can't get an answer.

      I already tried doing a cir of nat redirecting to the ip 10.10.1.3, I made rules in the ipsec, in the lan and I was not successful.

      they would have any idea to get this web service on the branch.
