Standard <strong>Sidewinder</strong> <strong>G2</strong> proxies<br />

The <strong>Sidewinder</strong> <strong>G2</strong> provides a variety <strong>of</strong> pre-defined proxies to<br />

control connections to popular Internet services using the standard<br />

port numbers for those services (see /etc/services for a list <strong>of</strong><br />

recognized protocols). Table 8-1 shows an alphabetical listing <strong>of</strong> the<br />

proxies that are preconfigured and can be quickly enabled using the<br />

Admin Console. To set up other proxies, see “Using other proxies on<br />

the <strong>Sidewinder</strong> <strong>G2</strong>” on page 8-13.<br />

During system installation, if you selected Standard Internet services,<br />

the proxies listed in bold are automatically enabled for internal<br />

network-to-external network, and corresponding proxy rules are<br />

added to the default active rule group.<br />
