86-0945853-B SmartFilter DA 4.0.1 Release Notes 9

General issues This section contains general issues you may encounter with SmartFilter DA

software.

Filtering through a NAT device

If a NAT device (such as a firewall, gateway router, or proxy server) is installed

between client computers and your IFP-enabled device (such as a Squid proxy

or Cisco PIX), certain SmartFilter DA functionality may not work as expected

(for example, user- and IP address-level filtering, authorized override, and

Monitor with Warning). To take advantage of all of SmartFilter DA's features,

install your IFP-enabled device between the NAT device and the client

computers.

SmartFilter DA cron jobs

SmartFilter DA installs the following cron jobs:

• Daily backup of admin database

• syncdb (upstream directory service synchronizer)

• Daily list verifier/submittal system

Configuring an SSL proxy

If you are installing SmartFilter DA in a private network that does NOT have

direct Internet access, and that has a proxy gateway that allows for outbound/

inbound HTTP/HTTPS traffic, enter the address and port for your upstream

proxy when prompted in the configuration wizard.

HTTPS and Squid

When browsing HTTPS blocked sites through a SmartFilter DA enabled Squid

Proxy, the user will receive a Squid error page instead of the standard

SmartFilter DA block page.

Available hotfix There is a possibility that low level administrators could access the custom

allow and block lists of the parent administrator. Hotfix 4.0.1.00.H01 is

available to eliminate this possibility. To obtain this hotfix, browse to
