I'm sorry, I don't understand. This system is already a slave for the
forward zone example.com. I just realized I forgot to include that in
my previous post:

zone "example.com" {
        type slave;
        file "slaves/db.example.com";
        masters { 64.1.1.3; };
        allow-query { any; };
        allow-transfer { trusted; };
};

Thanks,
Alex
