      Hello,

      I use Pfsense with CRAP and my provider can give us IP for free but we have to pay a fee for each IP with Internet access.
      So I can have 3 IP for free but I have to pay to have them reachable from outside.
      (Every addresses are on a public subnet, even if they don't have Internet access).

      So I configured the 2 IP as WAN on each Pfsense routers and the last one as CRAP.
      For now, only the CRAP address can access internet, to save money.

      My questions are :

      • do Pfsense (WAN IP) need to access the Internet to work properly ?
      • if not, can I use a "trick" to give Internet access to pfsense though the CRAP interface ?
        (for example to download snort updates….)

      I know this is a strange setup...
      Thanks you for your answers :)

        the answer most likely is in:
        http://doc.pfsense.org/index.php/Configuring_pfSense_Hardware_Redundancy_%28CARP%29#Setting_up_advanced_outbound_NAT

        more specifically, outbound NAT for localhost 127.0.0.0/8

          Yep, you're right I just figured this out 1 hour ago  ;D

          BUT this give the active gateway access to Internet, not the secondary one.

            correct, because the secondary doesn't have the CARP addresss. You would need internet access for the secondary addresses if you need both firewalls on the internet all the time.
