The two issues normally aren't related. If both connections are from the same provider, talk to them about multilink PPP; if they are from different providers, you need to look into multihoming and getting your own AS #. > Current setup: > freebsd 7.0 machine, one local IP address, runs web, mail, and name > server. > static ip address in router. > I have two DNS servers registered, but they both point to the same ip > address an the same machine.

In order to have redundancy, you need to have two real, separate machines, each of which is running BIND, each of which is on a separate routable IP. This is an orthogonal issue to setting up multiple Internet connections. > 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, -- -Chuck
