Need more information. That really depends on what services you use, what
operating systems you're using, your domain controller, where the firewall
is placed, whether you're talking about a desktop firewall on workstations,
etc. Really, if you have to ask that question, I think you're much better
off hiring or getting someone who knows the answer to that question to do it
for you. You wouldn't want a mistake in your firewall rules to cause you to
be hacked, for example.
