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.
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-DPG503.
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 Server List If creating a new entry, ignore this list.
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-DPG503 firewall. In this case, you can define the application as a “Special Application” in order to make it work. Note that the terms “Incoming”...
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.
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”...
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-DPG503 via the Internet. You can restrict access to a specified IP address or address range. External Filters Configuration –...

Advanced Features (continued) Using Remote Web-based Setup To connect to the XC-DPG503 from a remote PC via the Internet: 1. Ensure that both your PC and the XC-DPG503 are connected to the Internet. 2. Start your Web Browser. 3. In the Address bar enter: HTTP:// (Internet IP Address of the XC-DPG503) The Port number is also required.
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.
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 Firewall Exception System Firewall Exception Rules: The rules with which any received packets is complied, the packets will not processed by Firewall or NAT module, but to be processed directly by system protocol stack.
