Is promiscuous mode also required for SYNC (pfSync and XMLRPC) interface?

  • Dear Forum Members,

    Could you please help me understanding whether the promiscuous mode is also required for SYNC interface (dedicated to pfSync and XMLRPC), in addition to those interfaces hosting a functioning CARP VIP (e.g. WAN, LAN, OPT1/DMZ)?

    I know it may sound a silly question, but I'd like to avoid enabling that promiscuous mode on more VDS than the strictly required…

    Thank you in advance for your time and attention,


  • No promiscuous mode needed on interfaces that PFSYNC is running over.

  • Hi ssheikh, thanks a lot for your swift reply!

    I'll ask to enable the promiscuous mode only for WAN, LAN and OPT1 (DMZ) interfaces, than.

    Kind regards,
