  • Hi, i have two pfsense in active-pasove model.

    some time at day these firewall crash an reboot, when  the principal crash the backup up and some time it crash to.

    they don't have any strange setup, only firewall rule, CARP, nat, openvpn, dhcp, dns and squid.

    The machine is a Pentium(R) Dual-Core CPU E5300 whit 2GB in both machine.

    The network cars is :

    WAN1 (wan)      -> re0     
    LAN (lan)      -> em0       
    WAN2 (opt1)    -> re1       
    SYNCLAN (opt2)  -> re2

    The only not normal is that the log and crash report show that a one o two pc change the MAC address in loop, the log show this :
