foscolino

Hello,
I have configurated two pfsense in Bridge mode, replicated in carp setting.
I have two interface (OPT1 & OPT2) in Bridge mode:

OPT1(TO_L3)* -> igb1 -> NONE
OPT2(TO_L2)* -> igb2 -> NONE

All OK, but sometimes, when I try to ping a one address behind pfsense the ping not respond correctly,
and i see these tcpdump messages:

0:55:10.025136 00:23:ae:c4:d8:55 > 01:80:c2:00:00:0e, ethertype Unknown (0x88cc), length 60:

0x0020: 0000 0000 0000 0000 0000 0000 0000 ..............

If i try to ping same address after 5-10 minutes the ping respond correctly!
I don't know why...
These problems occurs on various addresses...
