Firewall Settings

The BiGuard S10 has a built-in firewall that provides an extra layer of protection from malicious
or unauthorized access to the network. Firewalls are the primary method for keeping a computer
secure from intruders. The BiGuard S10 firewall prevents harmful data from coming into and out
of a private network or a single computer. The firewall not only provides secure access to the
Internet, it also separates your company's public Web server from the company's internal net-
work. The firewall also keeps internal network segments secure from internal unauthorized
activity. See

Intrusion detection

The BiGuard S10 firewall features instruction detection capability. Intrusion detection alerts the
administrator when there has been unauthorized access to the network and provides intrusion
prevention features.

Block WAN request

The BiGuard S10 firewall can be set to block WAN requests from IP addresses that the router
determines are unauthorized.

WAN settings

The BiGuard S10 enables connection to an ISP using a static IP address, PPPoE protocol, or by
automatically obtaining an IP address using DHCP. The BiGuard S10 enables you to connect
using via the router or by using NAT (Network Address Translation). See

Static IP

A Static WAN connection will be configured according to the IP properties defined by your ISP.
In order to configure the BiGuard S10 for a Static WAN connection, you will need a static IP
address, subnet mask, default IP gateway, and DNS information from your ISP. See
the WAN for Static IP

PPPoE

Point-to-point protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP
frames in Ethernet frames. It is used mainly with cable modem and DSL services. It offers stan-
dard PPP features such as authentication, encryption, and compression. See

DHCP

By configuring DHCP settings, the device is able to get the IP settings automatically from the
