Maybe --possibly-- my own understanding is sorely lacking. Let me try to explain. The following requires a non-proportional font: Is this what your CARP setup looks like? external network | | OpenBSD#0 OpenBSD#1 | | internal network If so, are the CARP advertisements being sent via the external or internal network? OTOH, if you have a dedicated link, maybe your setup looks like this? external network | | OpenBSD#0--------OpenBSD#1 | | internal network I was under the impression that it should be possible to exchange CARP advertisements via the dedicated link (--------), though I have to admit that I haven't actually built such a network yet -- I'm planning to do that shortly. Maybe others can weigh in? regards, --ropers
