You're right.  I searched Yahoo, Alta Vista, etc. and didn't find much.
I think two nameservers on dual-homed bastion host works something like:

	/usr/sbin/named /etc/namedb/named.external.conf
	/usr/sbin/named /etc/namedb/named.internal.conf

	//
	// External nameserver config file
	//
	options {
		pid-file "/var/run/named.external.pid";
		listen-on {
			<EXTERNAL_IP>;
		};
		// other options
	};

	zone "my.domain" {
		type master;
		file "external.zone";
	};

	//
	// Internal nameserver config file
	//
	options {
		pid-file "/var/run/named.internal.pid";
		listen-on {
			<INTERNAL_IP>;
		};
		forwarders {
			<EXTERNAL_IP>;
		};
		forward only;
	};

	zone "my.domain" {
		type master;
		file "internal.zone";
	};

	# /etc/resolv.conf
	nameserver <INTERNAL_IP>
