Trying some test to see if carp and pfsync works, I get this issue: fw master works, all network connection works, then I disconnect che external interface cable of fw1 and carp0 go in INIT, carp1 in BACKUP and carp2 in BACKUP, on fw 2, carp0, carp1 and carp2 become MASTER. After 5/10 seconds, always with cable disconnected, the carp0 of firewall 1 is in INIT, carp1 and carp2 return to MASTER, and on fw2 the carp0 is MASTER and carp1, carp2 become BACKUP, and each 5/10 seconds fw1: carp0 INIT carp1 MASTER carp2 MASTER, after 5/10 seconds fw1 become carp0 INIT carp1 BACKUP carp2 BACKUP and so on.

Are you sure you see the same behavior if you set that value to 0 on both nodes, or alternatively to 1? /Johan
