Some applications require multiple connections, like Internet games, Video conferencing, Internet
telephony, etc. Because of the firewall function, these applications cannot work with a pure NAT router.
The Special Applications feature allows some of these applications to work with this product. If the
mechanism of Special Applications fails to make an application work, try setting your computer as the
DMZ host instead.
1.
Trigger: the outbound port number issued by the application..
2.
Incoming Ports: when the trigger packet is detected, the inbound packets sent to the specified
port numbers are allowed to pass through the firewall.
This product provides some predefined settings Select your application and click Copy to to add the
predefined setting to your list.
Note! At any given time, only one PC can use each Special Application tunnel.
4.5.3 Miscellaneous Items
IP Address of DMZ Host
DMZ (DeMilitarized Zone) Host is a host without the protection of firewall. It allows a computer to be
exposed to unrestricted 2-way communication for Internet games, Video conferencing, Internet
telephony and other special applications.
NOTE: This feature should be used only when needed.
Non-standard FTP port
You have to configure this item if you want to access an FTP server whose port number is not 21. This
setting will be lost after rebooting.
4.6 Security Settings
4.6.1 Packet Filter
Packet Filter enables you to control what packets are allowed to pass the router. Outbound filter applies
on all outbound packets. However, Inbound filter applies on packets that destined to Virtual Servers or
DMZ host only. You can select one of the two filtering policies:
1.
Allow all to pass except those match the specified rules
2.
Deny all to pass except those match the specified rules
You can specify 8 rules for each direction: inbound or outbound. For each rule, you can define the
following:
•
Source IP address
•
Source port address
•
Destination IP address
•
Destination port address
•
Protocol: TCP or UDP or both.
•
Use Rule#
For source or destination IP address, you can define a single IP address (4.3.2.1) or a range of IP
addresses (4.3.2.1-4.3.2.254). An empty implies all IP addresses.
For source or destination port, you can define a single port (80) or a range of ports (1000-1999). Add
prefix "T" or "U" to specify TCP or UDP protocol. For example, T80, U53, U2000-2999. No prefix
indicates both TCP and UDP are defined. An empty implies all port addresses. Packet Filter can work
with Scheduling Rules, and give user more flexibility on Access control. For Detail, please refer to
Scheduling Rule.
Each rule can be enabled or disabled individually.
Inbound Filter:
To enable Inbound Packet Filter click the check box next to Enable in the Inbound Packet
Filter field.
Suppose you have SMTP Server (25), POP Server (110), Web Server (80), FTP Server
(21), and News Server (119) defined in Virtual Server or DMZ Host.
Example 1:
(1.2.3.100-1.2.3.149) They are allow to send mail (port 25), receive mail (port 110),
and browse the Internet (port 80)
(1.2.3.10-1.2.3.20) They can do everything (block nothing)
Others are all blocked.
Example 2:
(1.2.3.100-1.2.3.119) They can do everything except read net news (port 119) and
transfer files via FTP (port 21)
Others are all allowed.
After Inbound Packet Filter setting is configured, click the save button.
Outbound Filter:
To enable Outbound Packet Filter click the check box next to Enable in the Outbound
Packet Filter field.
Example 1:
(192.168.123.100-192.168.123.149) They are allowed to send mail (port 25), receive
mail (port 110), and browse Internet (port 80); port 53 (DNS) is necessary to resolve
the domain name.
(192.168.123.10-192.168.123.20) They can do everything (block nothing)
Others are all blocked.
Example 2:
(192.168.123.100-192.168.123.119) They can do everything except read net news
(port 119) and transfer files via FTP (port 21)
Others are allowed
After Outbound Packet Filter setting is configured, click the save button.
4.6.2 Domain Filter
Domain Filter let you prevent users under this device from accessing specific URLs.
Domain Filter Enable
Checke if you want to enable Domain Filter.

Privilege IP Addresses Range
Setting a group of hosts and privilege these hosts to access network without restriction.
Domain Suffix
A suffix of URL to be restricted. For example, ".com", "xxx.com".
Action
When someone is accessing the URL met the domain-suffix, what kind of action you want.
Checke drop to block the access. Checke log to log these access.
Enable
Checke to enable each rule.
Example:
In this example:
1. URL include “sex.com” will be blocked, and the action will be record in log-file.
2. URL include “girl.com” will not be blocked, but the action will be record in log-file.
3. URL include “erotica.com” will be blocked, but the action will not be record in log-file.
4. IP address X.X.X.1~ X.X.X.10 can access network without restriction.
4.6.3 URL Blocking
URL Blocking will block LAN computers to connect to pre-defined Websites.
The major difference between “Domain filter” and “URL Blocking” is Domain filter require user to
input suffix (like .com or .org, etc), while URL Blocking require user to input a keyword only. In other
words, Domain filter can block specific website, while URL Blocking can block hundreds of websites
by simply a keyword.
URL Blocking Enable
Checked if you want to enable URL Blocking.
URL
If any part of the Website's URL matches the pre-defined word, the connection will be blocked.
For example, you can use pre-defined word "sex" to block all websites if their URLs contain
pre-defined word "sex".
Enable
Checked to enable each rule.
In this example:
1.URL include “sex” will be blocked, and the action will be record in log-file.
2.URL include “erotica” will be blocked, but the action will be record in log-file
3.URL include “girl” will not be blocked, but the action will be record in log-file.
4. URL include “game” will be blocked, but the action will be record in log-file
4.6.4 MAC Address Control
MAC Address Control allows you to assign different access right for different users and to assign a
specific IP address to a certain MAC address.
MAC Address Control
Check “Enable” to enable the “MAC Address Control”. All of the
settings in this page will take effect only when “Enable” is checked.
Connection control
Check "Connection control" to enable the controlling of which wired and
wireless clients can connect to this device. If a client is denied to connect
to this device, it means the client can't access to the Internet either.
Choose "allow" or "deny" to allow or deny the clients, whose MAC
addresses are not in the "Control table" (please see below), to connect to
this device.
Assosiation control
Check "Association control" to enable the
controling of which wireless client can
associate to the wireless LAN. If a client is
denied to associate to the wireless LAN, it
means the client can't send or receive any data
via this device. Choose "allow" or "deny" to
allow or deny the clients, whose MAC
addresses are not in the "Control table", to
associate to the wireless LAN.
Control table
"Control table" is the table at the bottom of the "MAC Address Control"
page. Each row of this table indicates the MAC address and the expected
IP address mapping of a client. There are four columns in this table:
MAC Address MAC address indicates a specific client.
IP Address
Expected IP address of the corresponding
client. Keep it empty if you don't care its
IP address.
When "Connection control" is checked,
check "C" will allow the corresponding
client to connect to this device.
When "Association control" is checked,
check "A" will allow the corresponding
client to associate to the wireless LAN.
In this page, we provide the following Combobox and button to help you to input the MAC address.
You can select a specific client in the “DHCP clients” Combobox, and then click on the “Copy to”
button to copy the MAC address of the client you select to the ID selected in the “ID” Combobox.
Previous page and Next Page
To make this setup page simple and clear, we have divided the
“Control table” into several pages. You can use these buttons to
navigate to different pages.
4.6.5 VPN setting
VPN Settings are settings that are used to create virtual private tunnels to remote VPN gateways. The
tunnel technology supports data confidentiality, data origin authentication and data integrity of network
information by utilizing encapsulation protocols, encryption algorithms, and hashing algorithms.
• VPN enable item
VPN protects network information from ill network inspectors. But it greatly degrades network throughput.
Enable it when you really need a security tunnel. It is disabled for default.
• Max. number of tunnels item
Since VPN greatly degrades network throughput, the allowable maximum number of tunnels is limited.
Be careful to set the value for allowing the number of tunnels can be created simultaneously. Its value
ranges from 1 to 5.
• Tunnel name
Indicate which tunnel that is focused now.
• Method
IPSec VPN supports two kinds of key-obtained methods: manual key and automatic key exchange.
Manual key approach indicates that two end VPN gateways setup authenticator and encryption key by
system managers manually. However, IKE approach will perform automatic Internet key exchange.
System managers of both end gateways only need set the same pre-shared key.
Function of Buttons
