The patch is not necessary for OpenBSD. We already detect such a
loopback condition. So, to repeat my question: Are you seeing the same
problems as you had with FreeBSD under OpenBSD?
I don't know VMWare too well, but I remember that their multicast
handling was somehow funny.
I would start without using load balancing.
Only if everything works as expected without, you can try turning it on.
However, there's no guarantee that ``balancing ip'' will work
with that virtual vmware switch. But I'm too lazy to explain why :)
Carp IP-Balancing has some known limitations (which I really should've
added to the manpage): It was meant to balance servers, not pf(4)
firewalls. Although it works for pf(4), the performance you gain isn't
that high and there are issues if you're using any kind of NAT.
HTH,
