CARP - DUAL WAN - WIFI



  • Hello, first sorry for my english, I will try to be as clear as possible in my questions.

    I'm planning to setup 2 computers with pfSense, each of them will have 4 network cards used like that :

    1. LAN
    2. WAN
    3. OPT1 (wifi access point)
    4. OPT2 (synchro between routers)

    I have 2 ADSL internet connexions (PPPOE) with dynamic IP addresses, I want them to work in Load Balancing mode, one connexion on the Master and one on the Slave.

    My first question is to know if that config is correct ? I have a big doubt, I think I saw somewhere that the Load Balancing was only working for static IP addresses or something like that, I hope I'm wrong …

    Now my second question :

    Do I have to plug one access point on each server and if yes, will they both be "online" or only one at the same time depending on the working server (Master or Slave) ?

    To be more clear, when I will search for a wifi network with a laptop, will I see 2 access points or only one like it should ?

    Feel free to give me any suggestions that you think more intelligent, I'm totaly lost about that wifi problem.

    I checked on the forums but found nobody speaking about the config I'm planning to setup.

    Thanks in advance for your help ! :)

    Here is your first issue. If you set it up this way, the failover will not be very clean and the slave connection will only be used when the master is down.
    Typically, you would use Two WAN ports on each computer, and connect both to both DSLs. In your case, two PPPoE WANs are not possible, and you would need a router between the second WAN and the DSL. Searching should provide detailed information on this.

    I would think the simple answer to this would be to setup your WIFI port like another LAN, connect the AP to a switch that is connected to the WIFI-OPT ports on both pfSense boxes and point the AP's gateway to the CARP address of the WIFI-OPT interface.
