Backup / Restore

These functions allow you to save and backup your router’s current settings to a file on your PC, or to restore a

previously saved backup. This is useful if you wish to experiment with different settings, knowing that you have a

backup handy in the case of any mistakes. It is advisable to backup your router’s settings before making any

significant changes to your router’s configuration.

Press

Backup

to select where on your local PC to save the settings file. You may also change the name of the file

when saving if you wish to keep multiple backups.

Press

Browse

to select a file from your PC to restore. You should only restore settings files that have been

generated by the Backup function, and that were created when using the

current version

of the router’s firmware.

Settings files saved to your PC should not be manually edited in any way.

After selecting the settings file you wish to use, pressing

Restore

will load those settings into the router.

When using Virtual Servers your PCs will be exposed to the degree specified in

your Virtual Server settings provided the ports specified are opened in your firewall

packet filter settings.

Firewall and Access Control

Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access from your LAN, as

well as helping to prevent attacks from hackers. Besides, when using NAT, the router acts as a “natural” Internet

firewall, as all PCs on your LAN will use private IP addresses that cannot be directly accessed from the Internet.

Firewall

: Prevents access from outside your network. The router provides three levels of security support:

NAT natural firewall

: This masks LAN users’ IP addresses which is invisible to outside users on the Internet,

making it much more difficult for a hacker to target a machine on your network. This natural firewall is on when NAT

function is enabled.

Firewall Security and Policy (General Settings)

: Inbound direction of Packet Filter rules to prevent unauthorized

computers or applications accessing your local network from the Internet.

Intrusion Detection

: Enable Intrusion Detection to detect, prevent and log malicious attacks.

Access Control

: Prevents access from PCs on your local network:

Firewall Security and Policy (General Settings)

: Outbound direction of Packet Filter rules to prevent unauthorized

computers or applications accessing the Internet.

URL Filter

: To block PCs on your local network from unwanted websites.

Here are the items within the

Firewall

section:

General Settings, Packet Filter, Intrusion Detection, URL Filter,

IM/P2P Blocking

and

Firewall Log.

General Settings

You

can

choose

not

to

enable

the

Firewall

and

still

have

access

to

URL

Filter

and

IM/P2P

Blocking,

or

you can

enable

the

Firewall

using

preset

filter

rules

and

modify

the

port

filter

rules

as

required.

The

Packet Filter

is

used

to

filter

packets

based-on

Applications

(Port)

or

IP

addresses.

There are four options when you enable the Firewall, they are:

²

All blocked/User-defined

: no pre-defined port or address filter rules by default, meaning that all inbound

(Internet to LAN) and outbound (LAN to Internet) packets will be blocked. Users have to add their own filter

rules for further access to the Internet.

²

High/Medium/Low security level:

the predefined port filter rules for High, Medium and Low security are

displayed in Port Filters of Packet Filter.

Select

either

High,

Medium

or

Low

security

level

to

enable

the

Firewall.

The

only

difference

between these

three

security

levels

is

the

preset

port

filter

rules

in

the

Packet

Filter.

Firewall

functionality

is

the same

for

all

levels;

it

is

only

the

list

of

preset

port

filters

that

changes

between

each

setting.

For

more detailed

on

level

of

preset

port

filter

information,

refer

to

Table

1:

Predefined

Port

Filter

.

If you choose of the preset security levels and add custom filters, this level of filter rules will be saved even and do

not need to re-configure the rules again if you disable or switch to other firewall level.

The

“

Block

WAN

Request

”

is

a

stand-alone

function

and

not

whether

security

is

enabled

or disabled.

Mostly

this

is

used

to

preventing

a

hacker

on

the

WAN

from

using

any

scan

tools.

(Changed the format only.)

Attempting

to

perform

this

action

remotely

may

result

in

blocking

of

all

access

to

and

of

the

from

the

Internet. Use

this

caution
