Hi Stephen,

I have been testing carp with the carpdev support for a few weeks now, 
and I too have noticed the issues you state in your previous posts 
regarding the default route of the BACKUP firewall when using carpdev on 
an addressless interface.

I am running a fresh install of 17th Feb snapshot on two identical test 
machines without preempt (advskew).

You mention "problem with the default route is fixed" in this post; I am 
interested to know how this is fixed, or rather how you came to know 
this.  Do you have an /etc/mygate, use bgpd, ifstated, routed?

Sorry if this is a little off topic for this thread but I am interested 
in your findings as you seem to be actively testing this setup like myself.


Regards,
Nigel.
