cachiing nameserver, did I miss something?

[Ed D.]

Hi,
    I've been working on setting up my firewall box to also act
as a caching nameserver for my network.
I THINK I might have it working, but want to be sure I did it right.
In the past, I thought I remembered there being a guide about how to
do this in the OpenBSD FAQ section.  I don't seem to be able to find
it anymore, so I've set out on my own.

As I said, it appears it's working, but I feel like there has to be
more to it, or that I'm missing the boat on something.
 Would appreciate any input on this.  Thanks,  Ed

    What I've done so far:
1. I've added the rndc-key to the end of named.conf in the
/var/named/etc subdirectory.

2. I've changed the named flags in rc.conf to
named_flags=""          # for normal use: ""

3. I have resolv.conf set to
lookup file bind

4. All the computers in the network are using the IP address of
the interface card that they connect to the firewall with as
the address of their dns.

When I run rndc status I get
meenon# rndc status
number of zones: 3
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 0/1000
tcp clients: 0/100
server is up and running
