My config is: Master [VRID] serverid = 5 interface = em0 useVMAC = yes sendgratuitousarp = yes priority = 255 addr=10.73.122.205/24, 10.2.200.1/32 masterscript = /usr/local/etc/master.sh backupscript = /usr/local/etc/backup.sh Backup [VRID] serverid = 5 interface = em0 useVMAC = yes sendgratuitousarp = yes priority = 250 addr=10.73.122.205/24, 10.2.200.1/32 masterscript = /usr/local/etc/master.sh backupscript = /usr/local/etc/backup.sh I posted this message to the freebsd-net group as well(actually by mistake, but thats another story), and as part of my investigations from replies received there, I was starting to believe that my problem was related to different types of network card/drivers. However, I have now built two boxes on identical hardware as well as a mixture of xl/em and things work fine. I am now starting to believe that the problems I experienced in freevrrpd may be as a result of having carp compiled into my kernel. The two new machines I have now built are stock 6.2, with no carp in the kernel. (Note, the original machines had no carp interfaces defined on them when using freevrrpd) I cant confirm fully until I am back in the office, but I will post back as soon as I am able. Kind Regards Ross
