[pfSense Support] CARP NIC overhead?

[Steve Harman]

Hi!   I’m spec’ing up a couple of machines to buy for running pfSense in a CARP-cluster model.  From reading the tutorial, am I right in thinking that this would require a NIC dedicated to the CARP functionality?   We need to provide a number of subnets so combined with the CARP NIC I’m trying to work out how many PCI slots (PC NICs) we need in each box!   Thanks,   Steve
