      HI
      I got a specific question regarding a specific design.

      I wnt to share a fiber connection between two companies.
      My isp give me two /30 subnet and ask i got this specific design:
      I need to have one specific router on first /30 and a second one with second /30.

      I implemented a pfsense as router 1 and all entry trafic is correct but i got one issue regarding existing trafic for second subnet.

      Indeed the design i understood is to connect fiber RAD to pfsense as igb1 (wan) then i implemented igb 1 as LAN1 and IGB 2 as second subnet /30.

      For first lan implemented on igb1 all is ok.

      For second one all renty trafic is ok but when i perfomr a myip.com query i got the wrong public IP.

      Can i force second LAn to not NAT trafic to first /30 but still second one regarding that second /30 is public ip?????

      I hope my query is clear if not don't hesitate to ask for more.....

        Finally i solve it myself using this link https://docs.netgate.com/pfsense/en/latest/interfaces/using-public-ip-addresses-on-an-interface.html

        The idea is to not ANT second /subnet as it s already an Public IP subnet.
