Chapter 3 - Advanced Port XC-DPG602 Twin WAN DNS → IP Gateway Chapter Contents • Overview • Port Options • Load Balance • Advanced PPPoE • Advanced PPTP Overview Port Options contains some options which can be set on either or both WAN ports. For most situations, the default values are satisfactory.Virtual Server Load Balance screen is only functional if you are using both WAN ports. It allows you to determine the proportion of WAN traffic sent through each port.
Port Options Figure 6. Port Options Connection Validation PPPoE / PPtP Connection Options Transparent Bridge Mode Health Check Use this field to select the type of connection validation to perform. When set to ICMP, the XC-DPG602 sends out ICMP echo requests. When set to HTTP, the XCDPG602 requests web pages. Auto Dialup When set to Enable a connection will be established whenever outgoing WAN traffic is detected. If not Enabled, you must establish a connection manually.
Load Balance Configuring Load Balancing The Twin WAN line of products uses a session based Load Balancing algorithm by allowing you to manage sessions using several different options: Bytes rx+tx By monitoring real time speed of both WAN connections, the XC-DPG602 will establish new sessions on the WAN port with the lower speed. Use this if there is a fairly even speed on both lines and would like to benefit the most from the speed available.
Advanced PPPoE Figure 8. Advanced PPPoE The screen is required in order to use multiple PPPoE sessions on the same WAN port. It can also be used to manually connect or disconnect a PPPoE session. Settings - Advanced PPPoE WAN Port Select the desired Port and Session, then click the “Select” button. The data for the selected Port/Session will then be displayed in the PPPoE Session WAN IP Account section. WAN IP Account Action Connection Status • User Name – Enter the PPPoE user name assigned by your ISP.

The data for the selected Port will then be displayed in the WAN IP Account section. WAN IP Account Action Connection Status • User Name – The PPTP user name (login name) assigned by your ISP. • Password – This field is associated with the User Name above. This is assigned by your ISP and used to login to the PPTP Server.
Chapter 4 - Advanced Setup XC-DPG602 Twin WAN DNS → IP Gateway Overview The following advanced features are provided. Chapter Contents • Host IP Setup • Virtual Server • Custom Virtual Server • Special Applications • Dynamic DNS • Multi DMZ • Advanced Features • UPnP Host IP Setup Virtual Server Custom Virtual Server Special Applications Dynamic DNS Multi DMZ Advanced Features UPnP This chapter contains details of the configuration and use of each of these features.
Host IP Host IP This feature is used in the following situations: When you have Multi-Session PPPoE and wish to bind each session to a particular PC on your LAN. When you wish to use the Access Filter feature. This requires that each PC be identified by using the Host IP Setup screen. When you wish to have different Block URL settings for different PCs. This requires that each PC be identified by using the Host IP Setup screen.
Virtual Servers Figure 10. Virtual Servers Virtual Servers This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: Your Server’s IP address is only valid on your LAN, not on the Internet. Attempts to connect to devices on your LAN are blocked by the firewall in the XC-DPG602.
Custom Virtual Servers Custom Virtual Servers This screen allows you to define your own Server types. This is for situations when the desired Server type is not listed on the Virtual Servers screen. Settings - Custom Virtual Servers Select Custom Server Name Custom Server Configuration Buttons Custom Virtual Server List Server List If creating a new entry, ignore this list. To edit an existing entry, select it, and then click the “Select” button. The screen will update with data for the selected entry.
Special Applications Special Application If you use Internet applications which have non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the XC-DPG602 firewall. In this case, you can define the application as a “Special Application” in order to make it work. Note that the terms “Incoming” and “Outgoing” on this screen refer to traffic from the client (PC) viewpoint.
Dynamic DNS Dynamic DNS Dynamic DNS is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect to your ISP. You must register for the Dynamic DNS service. The XC-DPG602 supports 2 types of service providers: Standard client, available at http://www.dyndns.org.
Multi DMZ & UPnP Dynamic DNS This feature allows each WAN port IP address to be associated with one (1) computer on your LAN. All outgoing traffic from that PC will be associated with that WAN port IP address. Any traffic sent to that IP address will be forwarded to the specified PC. This allows unrestricted 2-way communication between the “DMZ PC” and other Internet users or Servers. Note: The “DMZ PC” is effectively outside the Firewall making it more vulnerable to attacks.
Advanced Features Advanced Features NAT – NAT (Network Address Translation) is the technology which allows a number of LAN PCs to share one (1) Internet IP address. Remote Access Configuration – This feature allows you to manage the XC-DPG602 via the Internet. You can restrict access to a specified IP address or address range. External Filters Configuration – These settings determine whether or not the XC-DPG602 should respond to ICMP (ping) requests received from the WAN port.
Advanced Features (continued) Using Remote Web-based Setup To connect to the XC-DPG602 from a remote PC via the Internet: 1. Ensure that both your PC and the XC-DPG602 are connected to the Internet. 2. Start your Web Browser. 3. In the Address bar enter: HTTP:// (Internet IP Address of the XC-DPG602) The Port number is also required. (After the IP Address, enter “:” followed by the port number.) e.g.: HTTP://123.123.123.123:8080 • This example assumes the WAN IP Address is 123.123.123.
Chapter 5 - Security Management XC-DPG602 Twin WAN DNS → IP Gateway Chapter Contents • Block URL • Access Filter • Session Limit • Firewall Exception Overview Block URL - This feature blocks specific web sites by IP address, URL, or keywords. Access Filter - Block all Internet access, well-known ports, or block user define ports by groups. Session Limit - Eliminate users’ Internet access and send email alert to the administrator if the device detects new sessions that exceeds the maximum sampling time.
Block URL Block URL This feature allows you to block access to undesirable Web sites. You can block by URL, IP address, or Keyword. You can also have different blocking settings for different groups of PCs. Every URL is searched to see if it matches or contains any of the URL or keywords entered here. After a DNS lookup determines the IP address of the requested site, the site’s IP address is checked against IP address entries on this screen. Note that a single IP address may host many Web sites.
Session Limit & Firewall Exception Session Limit This new feature allows to drop the new sessions from both WAN and LAN side. If the new sessions number are exceed the maximum sessions in a sampling time. Settings - Session Limit Sample Time The period to count the� 400 mil-sec) Maximum of Total New session If the number of new sessions for system exceed the maximum in the Sampling Time. Any new sessions in the system will be dropped.
Chapter 6 - QoS Configuration Overview The XC-DPG602 provides QoS, which supports the high quality of network service.
