cannot get caching server to work from main DNS

[Kevin Darcy]

The 1.0.0.127.in-addr.arpa bogosity is caused by the fact that you forgot
to dot-terminate some names. But this probably doesn't have anything to
do with your main problem, which is that your nameserver isn't responding
to the "bumper" query. What does your hints file contain? Do you have
full connectivity to the servers that are listed in the hints file and
any other servers to which they may refer your server (and so on,
recursively)? If that's an Internet root hints file, then to use it
effectively, you'd have to be able to talk to *all* Internet nameservers.

Lastly, how do you *expect* "bumper" to resolve? What default domain or
search list do you have in /etc/resolv.conf? This will determine what
domain gets appended to the "bumper" label. Maybe all of the servers for
that particular domain are down or unreachable (?) If you have no default
domain or search list in /etc/resolv.conf, then "bumper" is going to be
queried in the root domain. Obviously, this is doomed to failure, not to
mention an annoyance for the root servers.
