Re: limit access to other LAN computers

[Pierre Jaury <pierre () jaury eu>]

Simplest way to deal with it, IMHO :
  _______
(       )_
(_Internet )
  (________)
      | (1)
  ____|_____
| Firewall |_____(2) _ _ DMZ
|__________|
      |
      |___ _(3)_ PAN

Configure a firewall so that every incoming connection will be
redirected to your DMZ (2) (with nat firewall rules if you do not have
many public addresses).
Then authorize machines on your private network (3) to access both the
Internet (1) and your Linux servers (2).

Set up a full user management system (based on Unix user accounts,
LDAP, ...) then a nfs+kerberos or ssh+ftp daemon, which will guarante
that every user is authenticated. You may also play with unix rights to
set up a complex access ruleset.

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
