Installation#5. Which machine should DansGuardian/Squid be installed on?
For a single user system, DansGuardian/Squid should be installed directly onto the single computer. For a network of users, DansGuardian/Squid is often installed on the gateway/firewall machine itself. DansGuardian/Squid can also be installed on a separate server, rather than directly on the gateway/firewall server. The separate DansGuardian/Squid server can either be on the LAN itself (probably near the gateway/firewall), or in a DMZ (De-Militarized Zone, i.e. half in/half out).
