Conventional wisdom says you should do no such thing, never allow the
general public direct access to a machine your Intranet. If anyone ever
gains full access to the host you run your web server on your intranet is
completely compromised. Usually web servers are put on a separate
(sub-)network that is accessible to the public. The real intranet is
protected by a 'firewall', a combination of hardware and software supposed
to keep your internal network secure.
Start out with reading "Building Internet Firewalls" by D. Brent Chapman and
Elizabeth D Zwicky (O'Rielly & Assoc. ISDN 1-56592-124-0).
The cost? If you have the appropriate skills you can conceivably build a
firewall yourself using free software (Linux of FreeBSD, two Ethernet cards,
and the TIS firewall toolkit). I've done this once, using an old 486 PC. You
really need to know what you're doing, so read that book and the TIS manual.
The alternative is buying a solution. It all depends on the skills available
in your company, how secure your network needs to be, and your budget.
