HELP! Firewall blocking same subnet



  • Dec 6 05:30:57 WAN 149.217.134.211 149.217.134.186 ICMP

    WAN : 149.217.134.184/29 (255.255.255.248)
    OPT1 : 149.217.134.0/24  (255.255.255.0)
    LAN : 10.0.0.0/24

    When a host on OPT1 ping my WAN it is blocked by the firewall.

    ???

    How to fix this?
    Thanks



  • If i activate this option, i can ping my WAN interface no problem.

    Shared Physical Network
      This will suppress ARP messages when interfaces share the same physical network

    But it won't work with NAT, it's trying to access my server internal ip address…

    Dec 6 05:47:36 WAN 149.217.134.254:3142 10.0.0.2:21 TCP
    Dec 6 05:47:33 WAN 149.217.134.251:1028 10.0.0.2:53 TCP

    PFSENSE thinks both network are on the same subnet, but they are not!!!

    Thank you so much!!!



  • This is crazy!!

    Now for no apparent reason I can't PING my WAN !? 30 minutes ago I could!!!

    Dec 6 06:28:37  WAN  149.217.134.211  149.217.134.186  ICMP

    Help me please. Thank you.



  • @charles.regan:

    Sure they are! 149.217.134.0/24 includes 149.217.134.184/29. There is no router in the whole wide world that can handle this  ;)
