If we are talking in absolutes, the answer is no. Otherwise, the answer
is, for the most part, yes.
Look into firewalls, IP Masquerading/NAT, proxies and private IP ranges.
Firewalls allow you to choke off selected communications.
IP Masquerading/NAT allow you to conceal the identity and number of
computers accessing the net from your site.
Proxies can do a number of things, and are a kind of half-step between
firewalling and IP Masquerading, but can have some added bonuses (content
filtering, content caching, etc).
Private IP ranges allow you to use addresses in your system that are
invalid on the global internet (10.0.0.0/8, 192.168.0.0/16, and there is
one more I can never remember), and can be used in conjunction with
masquerading or proxies (or both) to add to the confusion of an intruder.
Also look into port forwarding. This is a service where a firewall with
masquerading will take a request and send it to a specific server, e.g. if
the firewall is accessed on port 25, it will connect you to an internal
mail server.
Hope this helps.
