A higher advskew (Advertising Frequency Skew) will lower its advertisements and renders the node less attractive of being a master. Skewness is a measure of the asymmetry of a distribution. I think this is a bug that if the CARP skew setting syncs, something happens to the backup so it has a blank Status and no longer considers itself the Backup for that interface, and therefore This seems to me to be a FreeBSD bug, setting advskew to 0 never works. pfSync Together with CARP, we can I discuss some of the basics and settings for pfSense in High Availability as well as going through the CARP interfaces, SYNC interface for pfsync, Virtual I In this video, I will show you how to set up network-wide ad-blocking and tracking protection using pfSense and AdGuard Home.
