Greetings

I'm new to OpenBSD & pfSense and I'm currently looking into a pfSense cluster setup exactly as described in Fig.2 http://forum.pfsense.org/index.php/topic,1014.0.html.
In order to avoid having the switch as single point of failure I would like to connect each pfSense to a separate switch (which is interconnected with its own trunking feature).

I have come across the trunk(4) feature in OpenBSD which means I can setup two NICs as a virtual NIC and let them act as an active/standby pair (I guess the failure criteria is the media link up/down).

My question is would the CARP feature work on top of such a virtual NIC (setup IP, MAC….)?

Thanks for any hints,

FWIW, we don't run on OpenBSD.  So, no this feature won't work and I dunno if it'd work as you describe in Open.
