I have a client using Linux firewall as proxy to internet and other Linux boxes running DNS internally, problem is every PC has to be entered into DNS otherwise brosing is very slow
try www.linux.org for more help. But to give you help, although this is a Cisco help/forum, the DNS server you setup may be configured to only allow request from 'known' hosts or 'reversable' hosts.
Good luck!
