Front Panel Leds - McAfee SG310 Administration Manual

Introduction
UTM Firewall desktop appliances
The SG560, SG560U, SG565, and SG580 can also connect to a DMZ (DeMilitarized Zone) network. A DMZ is
a separate local network typically used to host servers accessible to the outside world. It is separated both
physically and by the firewall, in order to shield your LAN from external traffic.
The UTM Firewall appliance allows you to establish a VPN (Virtual Private Network). A VPN enables remote
workers or branch offices to connect securely to your LAN over the public Internet. The UTM Firewall
appliance can also connect to external VPNs as a client. The SG560, SG560U, SG565, and SG580 use
onboard cryptographic acceleration to ensure excellent VPN throughput.
You can configure the appliance with multiple Internet connections. These auxiliary connections can be kept
on standby should the primary connection become unavailable, or maintained concurrently with the
primary connection for spreading network load.
The SG565 and SG580 incorporate a powerful Web proxy cache to improve Web page response time and
reduce link loads. It is designed to integrate seamlessly with upstream proxy caches provided by ISPs.
