Okay, so your FreeBSD box is also acting as a router.
You should therefore set up BIND/named locally, and tell dhclient (or
whatever you're using to fetch an IP address from your ISP) to **not**
modify resolv.conf. Make note of what those nameserver IPs are though,
you'll need them below.
Pick a "fake domain" for yourself (such as home.lan or something that
won't be used on the Internet; a fake TLD is the way to go).
Make sure your machine name is set in rc.conf to a FQDN, such as
myboxname.home.lan. You can set this without rebooting by doing (as
root) "hostname myboxname.home.lan".
Next, you should go into /etc/namedb and run "sh make-localhost" as
root. If you've done this in the past, you should do a rm
/etc/namedb/master/localhost-v6.rev /etc/namedb/master/localhost.rev
first.
In your named.conf, you'll claim to be authoritative for home.lan and
declare it as such via a zone "home.lan" {} container. See below.
Finally, you should declare a list of forwarders in options {} which
your nameserver will forward all recursive DNS queries through (it will
still answer for anything it claims to be authoritative for, such as
home.lan). DO NOT use "forward only".
Example (taken from my own setup at home, where 192.168.1.51 *is not*
a router, but if it was, I'd tell dhclient or whatever *not* to
modify resolv.conf :-) ):
/etc/rc.conf
============
hostname="icarus.home.lan"
ifconfig_nve0="inet 192.168.1.51 netmask 255.255.255.0"
defaultrouter="192.168.1.1"
/etc/hosts
==========
127.0.0.1 localhost localhost.home.lan
192.168.1.51 icarus.home.lan icarus
/etc/resolv.conf
================
