Question about ipsec configuration

  • Hello, I have a customer that needs to connect with an external office with special IPSEC configuration. No problem with phase1 and 2 configs, but in generic specifications document says:

    The basic parameters will be:

     Fixed public IPv4 Addressing for the VPN gateways is mandatory
     The MTU will be established to 1310 inside the tunnel
     IPSec VPN tunnel routed mode (using proxy-id's, named VTI mode by Cisco)

    Does anyone know how can I configure pfsense with 3rd point? is it possible or only with Cisco?
