a.
Account:
Enter your Account Name (may also be called Host Name) and Domain Name.
These parameters may be necessary to access your ISP’s services such as mail or news
servers.
b.
Internet IP Address:
If your ISP has assigned you a permanent, fixed (static) IP address for your PC, select
“Use static IP address”. Enter the IP address that your ISP assigned. Also enter the
netmask and the Gateway IP address. The Gateway is the ISP’s firewall to which your
firewall will connect.
c.
Domain Name Server (DNS) Address:
If you know that your ISP does not automatically transmit DNS addresses to the firewall
during login, select “Use these DNS servers” and enter the IP address of your ISP’s
Primary DNS Server. If a Secondary DNS Server address is available, enter it also.
Note:
After completing the DNS configuration, restart the computers on your network so
that these settings take effect.
d.
Firewall’s MAC Address:
This section determines the Ethernet MAC address that will be used by the firewall on the
Internet port. Some ISPs will register the Ethernet MAC address of the network interface
card in your PC when your account is first opened. They will then only accept traffic from
the MAC address of that PC. This feature allows your firewall to masquerade as that PC
by “cloning” its MAC address.
To change the MAC address, select “Use this Computer’s MAC address.” The firewall
will then capture and use the MAC address of the PC that you are now using. You must be
using the one PC that is allowed by the ISP. Or, select “Use this MAC address” and
enter it.

to save your settings.
4.
If your Internet connection does require a login, fill in the settings according to the instructions
below. Select Yes if you normally must launch a login program such as Enternet or WinPOET
in order to access the Internet.
Note:
After you finish setting up your firewall, you will no longer need to launch the ISP’s
login program on your PC in order to access the Internet. When you start an Internet
application, your firewall will automatically log you in.

Chapter 4
Firewall Protection and
Content Filtering
This chapter describes how to use the content filtering features of the FVS114 ProSafe VPN
Firewall to protect your network. These features can be found by clicking on the
Security
heading
in the main menu of the browser interface.
Firewall Protection and Content Filtering Overview
The FVS114 ProSafe VPN Firewall provides you with Web content filtering options, plus
browsing activity reporting and instant alerts via e-mail. Parents and network administrators can
establish restricted access policies based on time-of-day, Web addresses and Web address
keywords. You can also block Internet access by applications and services, such as chat or games.
A firewall is a special category of router that protects one network (the trusted network, such as
your LAN) from another (the untrusted network, such as the Internet), while allowing
communication between the two. A firewall incorporates the functions of a NAT (Network
Address Translation) router, while adding features for dealing with a hacker intrusion or attack,
and for controlling the types of traffic that can flow between the two networks. Unlike simple
Internet sharing NAT routers, a firewall uses a process called stateful packet inspection to protect
your network from attacks and intrusions. NAT performs a very limited stateful inspection in that
it considers whether the incoming packet is in response to an outgoing request, but true stateful
packet inspection goes far beyond NAT.
To configure these features of your firewall, click on the subheadings under the
Security
heading
in the main menu of the browser interface. The subheadings are described below:

Block Sites
The FVS114 allows you to restrict access based on Web addresses and Web address keywords. Up
to 255 entries are supported in the Keyword list. The Block Sites menu is shown in
Figure 4-1
:
Figure 4-1:
Block Sites menu
Web Components
: You can use these to block undesirable Web componenents or behavior. Select
the desired options:
Turn Proxy filtering on: Block use of a remote Proxy Server. A Proxy Server can be used to
hide the real name or address of the site which your LAN users are connecting to. By enabling
this option, you force LAN users to connect directly, so their activity can be logged and/or
blocked.
Turn Java filtering on: Block Java applets.
Turn ActiveX filtering on: Block ActiveX components (OCX files) used by IE on Windows,
and by Windows Update.
