jimp was referring to the requirement that a CARP VIP must be contained in the same subnet as the interface address. Removal of that requirement/limitation is what changed. The VHID is 8 bits and you can’t use 0 so 1-255. As discussed there, make IP Alias VIPs and assign them to CARP VIPs. They will go up and down with CARP MASTER/BACKUP status and will result in no additional multicast traffic per VIP. Try it I think you’ll like it. _______________________________________________ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
