Virtual Server 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 the details, please refer to Scheduling Rule. For example, if you have an FTP server (port 21) at 192. 168. 123. 1, a Web server (port 80) at 192. 168. 123. 2, and a VPN server at 192. 168. 123. 6, then you need to specify the following virtual server mapping table: 23 Service Port 21 80 1723 Server IP 192. 168. 123. 1 192. 168. 123. 2 192. 168. 123. 6 Enable V V V Click on "Save" to store your settings or click "Undo" to give up the changes. Special AP 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 inbound packets sent to the specified port numbers are allowed to pass through the firewall. This device provides some predefined settings. Select your application and click "Copy to" to add the predefined setting to your list. Click on "Save" to store your settings or click "Undo" to give up the changes. 24 Miscellaneous 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. If the OS of your client computer supports this function, and you enabled it, like Windows XP, you can see the following icon when the client computer gets IP from the device. Click on "Save" to store your settings or click "Undo" to give up the changes. Security Setting Packet Filters Packet Filter includes both outbound filter and inbound filter. Packet Filter enables you to control what packets are allowed to pass the router. However, inbound filter applies on packets that destined to Virtual Servers or DMZ host only. You can select one of the two filtering policies: 25 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 · Destination IP address · Destination port · 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). 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. [. . . ] TEW-656BRG ­ 3 Years Warranty AC/DC Power Adapter, Cooling Fan, and Power Supply carry 1 year warranty.
