[Solved] Multi NAT



  • Hi all,

    I have a little problem and i hope you can help me.

    I must change all my ip from 192.168.1.0/24 to 10.52.1.0/24 but i can't do it (i don't have access of the configuration of all peripherals).

    So i want to install pfsense for translate in the 2 way :

    WAN                                                                    LAN
    SOMETHING TO 10.52.1.2 ==> PFSENSE ==> TO 192.168.1.2
    And
    SOMEWHERE FROM 10.52.1.20 <== PFSENSE <== TO SOMEWHERE FROM 192.168.1.20

    I tried 1:1 Nat with this configuration

    Virtual IP :

    • Address : 192.168.1.0/24
    • Interface : WAN
    • Type : Proxy ARP
      Nat 1:1 :
    • Interface : Wan
    • External IP : 10.52.1.2
    • Internal IP : 192.168.1.2
    • Destination IP : *
      Firewall rules for open all.

    And it's works perfectly.

    But i want to Nat the entire network in the 2 ways (i don't want to create all 1:1).

    I have removed the 1:1 mapping and i tried differents configuration on Outbound but no one works.

    Anyone now how to do it ?



  • 1:1 NAT has the ability for mapping an entire network.
    At "External subnet IP" enter the first external address, at "Internal IP" select Network and enter the first internal address and the subnet mask.



  • What's works. Thank you very much
