Yes, In an ideal world I would do this. The two machines would also be in separate buildings/cities/provinces/countries/planets (pick your level of paranoia)=A0 ;) However, reducing single points of failure is an improvement, even if I can't eliminate them. > > > How do I set up bind so that > > 1) bandwidth is shared between the two connections, > > and > > 2) if one goes down, the other keeps working. > > I had a few ideas, but they all seem to have flaws. > > You can't set up BIND to control multilink aggregation and failover; > that's not what it does. > > Regards, > -- freebsd-questions@freebsd.org > -Chuck > Thanks for the replies. Chuck, thanks for the keywords to search. Some of what I'm finding looks like a solution for companies a lot bigger than me, but I'll keep looking. Gary, can you give me any clues about how to do it with just DNS? Yes, I do realize that this leaves single points of failure, but at least they would be points that I could do something about if necessary.
