Meant to reply to this at the time, but have been away... > Has anyone else run into problems when using IPv6 + CARP ? I ran into some - aliases on a CARP integface did not seem to work proprly - but if you workaround that then it appears to work fine. We are using it in production with no problems. > I plan to hold a presentation at work on IP6 and why we should start > using it, however I cannot promote the use of IP6 without redundancy > between firewalls like we currently do with CARP + pfsync. The redundancy with pfsync works properly - an ssh session is maintained through the firewalls when they failover. I configure my machines to use a paiur of carp interfaces on each physical port, so I am not mixing IPv4 and IPv6 on the same interface. I onyl did that as an experiment when I was trying to work around the aliases problem, but have kept it for "tidnyess" Basically our experience of the setup has been very positive - our main connectivity issues have come from the HE/Cogent peering squabble rather than any FreeBSD/Carp/PF failing. cheers, -pete.
