VMS is perfectly happy with two NI interfaces. Both have the same DECnet address and therefore the same MAC and are presumably connected to different physical networks. It'd be a mess if you connected them both to the same LAN segment, of course. IF the VMS node is a router, it'll happily route DECnet traffic between the two interfaces and their associated networks. I'm doing it now - LEGATO is configured this way. I'm starting to think the problem lies with simh interfacing with FreeBSD's netstack/some odd OpenVPN stuff.
