I first want a firewall with failover. _Then_ if it works,

not helpful. the synch state demon only keeps track of the ipvs controlled connections, not the firewall state.

Running a firewall on the director with failover is a fairly normal operation now. It doesn't use carp/pfsync.

but when the masters fails every connection tracked
by the firewall are lost. I want to avoid that.

ah. I see. Yes this is a problem. I had assumed this was solved a long time ago (scratching head....) I now remember Harald Welte talking about writing this at an OLS a few years back, but he hadn't found sponsorship to do it and was putting it off. A quick search of Harald's web pages just now with google doesn't turn up anything likely.

This is most unfortunate.
