• URL include “www.msn.com” will be blocked, and the action will be record in log-file. • URL include “www.sina.com” will not be blocked, but the action will be record in log-file. • URL include “www.google.com” will be blocked, but the action will not be record in log-file. • IP address X.X.X.1~ X.X.X.20 can access network without restric- tion. 4.5.2 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: • Allow all to pass except those match the specified rules • 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 ( or a range of IP addresses ( An empty implies all IP addresses.
Page: 20
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 Inbound filter button and 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 ( They are allow to send mail (port 25), receive mail (port 110), and browse the Internet (port 80) ( They can do everything (block nothing) Others are all blocked. Example 2
Page: 21 Outbound Filter: To enable Outbound Packet Filter click the check box next to Enable in the Outbound Packet Filter field. Example 1 ( 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. ( They can do everything (block noth- ing) Others are all blocked.
Page: 22
Example 2 ( 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. 4.5.3 MAC CTRL (MAC address access 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 ad- dress. • MAC Address Control: Check “Enable” to enable the “MAC Ad- dress Control”. All of the settings in this page will take effect only when “Enable” is checked.
Page: 23
• Connection control: Check "Connection control" to enable the controlling of which wired 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. Controltable "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. C When "Connection control" is checked, check "C" will allow the corresponding client to connect to this device. 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. 4.5.4 Misc.

4.6 Advanced settings 4.6.1 Virtual Servers This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so all hosts behind this product are invisible to the outside world. If you wish, you can make some of them accessible by enabling the Virtual Server Mapping. A virtual server is defined as a Service Port, and all requests to this port will be redirected to the computer specified by the Server IP. Virtual Server can work with Scheduling Rules, and give user more flexibility on Access control. For Detail, please refer to Scheduling Rule. For example, if you have an FTP server (port 21) at, a Web server (port 80) at, and a VPN server at, then you need to specify the following virtual server mapping table: Service Port Server IP Enable 21 V 80 V 1723 V 4.6.2 Special Applications
Page: 26
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. • Trigger: the outbound port number issued by the application.. • Incoming Ports: when the trigger packet is detected, the in- bound 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. 4.6.3 Misc

The items you have to setup including: IP Address for Syslog Host IP of destination where syslogs will be sent to. Check Enable to enable this function. IP addres of Outgoing mailserver Input the SMTP server IP and port, which are concated with ':'. If you do not specify port number, the default value is 25. For example, "mail.your_url.com" or "". Log or Alart recipient The recipients who will receive these logs. You can assign more than 1 recipient, using ';' or ',' to separate these email addresses. 4.6.6 DDNS (Dynamic DNS) To host your server on a changing IP address, you have to use dynamic domain name service (DDNS).
Page: 29
So that anyone wishing to reach your host only needs to know the name of it. Dynamic DNS will map the name of your host to your current IP address, which changes each time you connect your Internet service provider. Before you enable Dynamic DNS, you need to register an account on one of these Dynamic DNS servers that we list in provider field. To enable Dynamic DNS click the check box next to Enable in the DDNS field. Next you can enter the appropriate information about your Dynamic DNS Server. You have to define: • Provider • Host Name • Username/E-mail • Password/Key You will get this information when you register an account on a Dynamic DNS server. 4.6.7 SNMP In brief, SNMP, the Simple Network Management Protocol, is a protocol designed to give a user the capability to remotely manage a computer network by polling and setting terminal values and monitoring network events. Enable SNMP You must check either Local or Remote or both to enable SNMP function. If Local is checked, this device will response request from LAN.
