Hi,

i worked the last days on non working setup with carp and bridges. And be sure
that the bad gateway is not your stopping problem. This is only a missing
check in the arp code for the virtual carp ethernet addresses. If
destroy nothing-:)

I had also on strange effect which is something like stopping.
I saw that everything is getting to be really slow on the network of
one machine.
If i say i mean slow so a ping could get a roundtrip time of 10
minutes. I didn't discovered the cause of these but the only solution
was to reboot.

My feeling is that carp doesn't like to receive packets which have the same
vhid but are coming from a different carpxxx than the own one. This is only
a idea it is not prooved.... There has to do further investigation to
find this problem.
I never had the problem if my setup was stable and i stop to play around-:)

Perhaps I can set up a route for the virtual IP address manually because the kernel keeps on complaining: "arp_trequest: bad gateway (!AF_LINK). This is weired because my carp setup is working for the past 4 days and it suddenly stopped with the above error.
