You have to tell the other machines on your network to use the IP of the
local DNS server for domain name resolution. If you are using DHCP you can
configure your DHCP server to give this information with the IP. Otherwise
you must manually do it, which will be different between operating systems.
HINT: In FreeBSD add the IP of the DNS server to /etc/resolve.conf
