This is really a bind question and there are more approipate forums for
that. (cxomp.protocols.dns.bind) However I'll see if I can help. You seem
to be saying you want to run a DNS service for your domain from your two
ADSL connections.

First thing I'd say is that it is better to get you ISP to provide the
published DNS primary and secondary servers while you run some sort of
hidden primary DNS server which your ISP takes domain updates from. Much
safer in that a long ADSL outage wont cause flow problems with things like
mail, but you still directly control DNS updates.

Secondary the internal (for your internal network) DNS scheme is a little
tricker. Depends on whether you have an internal VPN. You should run two
internal (split) DNS servers, one as master for the internal domain
structure, the other a secondary.
