Hi Stefan, i'm not doing load balance, just active/passive router/firewall configuration, but we're using only one ip on carp, with no ip address on the phisical interfaces. Our configuration is like this: # cat /etc/hostname.fxp0 up
# cat /etc/hostname.carp0 inet 81.xx.xx.xx 255.255.255.252 81.xx.xx.xx vhid 1 carpdev fxp0 same thing on the other machine (with advskew 100) Hope this helps Rick On Sun, Oct 9, 2011 at 7:01 PM, Stefan Midjich <sweh...@gmail.com> wrote: > Everything I read about CARP, including my Book on PF 2nd edition, > says you're supposed to have two different ip-addresses set for each > carp device, for two hosts that is.
