If you want free DNS hosting, check out
http://soa.granitecanyon.com
http://www.mydomain.com
You can use these systems as primary DNS, or as secondary (they get their
information from some other computer; presumably your personal machine).

Those are hosts, not subdomains. You'll need to run a DNS server (BIND,
djbdns, or others) to resolve queries for the outside world. You'll also
need to update your DNS primary server IP to point to your machine. Note
that if your IP changes (DHCP over a cable modem, for example), this may not
be a great idea.

If your DNS server is OUTSIDE the firewall, all will work without problems;
your internal machines will query it without problems.
If your DNS server is INSIDE the firewall, you'll have to forward ports
accross (port 53, TCP and UDP) to get to the DNS server in order for DNS
queries to resolve correctly from the outside.
Finally, I highly recommend O'Reilly's "DNS and Bind" book (the one with a
dragonfly on the cover) if you're going to get heavily into DNS.
Hope that helps some.
