A Google search turned up a thread from a couple of years ago that almost echoed my exact words. We've got a system with network interfaces on two disjointed networks. No routing is desired, but we very much want for both interfaces to be accessible from the world so each interface has to know about its nearest gateway just as the primary interface knows about the default route. What one seems to always be able to do is get the primary up and talking to the world with no real trouble. The secondary is on its network and you can log in from another host on the same subnet but you can never see it from the world, at large. Before the thread died out, the questioner was wondering if it was simply not possible to achieve this functionality. I am wondering the same. We are moving a primary name server from network A to network B on one of our branch campuses. If the secondary interface was reachable from the world, we can change the whois information and not worry about the exact second the change goes in to effect. The DNS should just answer whether the query came from network A or Network B. The routing is already handled so the system in question just has to be there and respond on both networks for a day or so. We don't have a spare box to run on the new network space or I would have done that days ago.;-( Again, thanks for any ideas.
