      Hi!
      I need a IPSec tunnel between my LAN (with pfSense 2.4.5) and other LAN (with Fortinet, I'm not sure, but it's not pfSense). The IT of the other company tells to me the both LANs is in the same range (192.168.0.X), and the IPSec doesn't work. They say me put another IP address, or create NAT. How?
      The other company suggest me the next schema:
      My LAN (192.168.0.X) ---Translate to 192.168.10.x for example <--- IPSec ---> LAN 'of them' (192.168.0.X)
      Can I put another IP Range to my LAN? How can both see, or comunicate?
      Thanks

        NAT in IPSec is done in your Phase 2 config.
