I finally got CARP _working_ :)
I've a problem when I do "ifconfig carp1 down" on the MASTER host to
test if BACKUP takes over the traffic..
It does work so far. But the problem is that if I'm streaming Internet
radio or are connected to IRC the radio will get stalled when I do
"ifconfig carp1 down" on MASTER, and the IRC disconnects and then
tries to reconnect which of course works.
I think something is wrong, since it shouldn't affect the traffic flow
at all when MASTER interrupt.
I have three interfaces in each host. and my setup looks like
(here is a diff link http://pastebin.com/pastebin.php?diff=749904)

And pf.conf at both hosts are identical:
# cat /etc/pf.conf
set loginterface fxp0
nat on hme0 from rl0:network to any -> hme0
pass in on hme0 all
pass out on hme0 all
pass quick on { fxp0 } proto pfsync keep state
pass on { hme0 rl0 } proto carp keep state
any suggestions are welcome
