Set Up a Default DMZ Server

The default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The cable modem router is programmed to recognize some of these applications and to work correctly with them, but other applications might not function well. In some cases, one local computer can run the application correctly if the IP address for that computer is entered as the default DMZ server.

Warning: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network.

The cable modem router usually detects and discards incoming traffic from the Internet that is not a response to one of your local computers or a service that you configured in the Port Forwarding/Port Triggering page. Instead of discarding this traffic, the cable modem router can forward the traffic to one computer on your network. This computer is called the default DMZ server.

Subnet mask. 255.255.255.0

Specify Network Settings 57 User Manual

AC1750 WiFi Cable Modem Router

These addresses are part of the designated private address range for use in private networks and are suitable for most applications. If your network requires a different IP addressing scheme, you can change these settings.

You might want to change these settings if you need a specific IP subnet that one or more devices on the network uses, or if you use competing subnets with the same IP scheme.

To change the LAN TCP/IP settings:

Specify the IP Addresses That the Cable Modem Router Assigns

Set Up and Manage Dynamic DNS

Internet service providers (ISPs) assign numbers called IP addresses to identify each Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP address can change at any time. You can use the IP address to access your network remotely, but most people don’t know what their IP addresses are or when this number changes.

To make it easier to connect, you can get a free account with a Dynamic DNS service that lets you use a domain name to access your home network. To use this account, you must set up the cable modem router to use Dynamic DNS. Then the cable modem router notifies the Dynamic DNS service provider whenever its IP address changes.

When you access your Dynamic DNS account, the service finds the current IP address of your home network and automatically connects you.

If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private addresses are not routed on the Internet.

Application Example: Make a Local Web Server Public

If you host a web server on your local network, you can use port forwarding to allow web requests from anyone on the Internet to reach your web server.

To make a local web server public:

1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation.In this example, your cable modem router always gives your web server an IP address of 192.168.0.33.2. On the Port Forwarding/Port Triggering page, configure the cable modem router to forward the HTTP service to the local address of your web server at 192.168.0.33. HTTP (port 80) is the standard protocol for web servers.3. (Optional) Register a host name with a Dynamic DNS service, and specify that name on the Dynamic DNS page of the cable modem router.Dynamic DNS makes it much easier to access a server from the Internet because you can type the name in the Internet browser. Otherwise, you must know the IP address that the ISP assigned, which typically changes.

Destination address. The IP address of www.example.com, which is the address of your cable modem router.
Destination port number. 80, which is the standard port number for a web server process.

2. Your cable modem router receives the message and finds your port forwarding rule for incoming port 80 traffic.3. The cable modem router changes the destination in the message to IP address 192.168.0.123 and sends the message to that computer.4. Your web server at IP address 192.168.0.123 receives the request and sends a reply message to your cable modem router.5. Your cable modem router performs Network Address Translation (NAT) on the source IP address, and sends the reply through the Internet to the computer or mobile device that sent the web page request.

Set Up Port Triggering

Port triggering is a dynamic extension of port forwarding that is useful in these cases:

An application must use port forwarding to more than one local computer (but not simultaneously).
An application must open incoming ports that are different from the outgoing port.

With port triggering, the cable modem router monitors traffic to the Internet from an outbound “trigger” port that you specify. For outbound traffic from that port, the cable modem router saves the IP address of the computer that sent the traffic. The cable modem router temporarily opens the incoming port or ports that you specify in your rule and forwards that incoming traffic to that destination.

Port forwarding creates a static mapping of a port number or range of ports to a single local computer. Port triggering can dynamically open ports to any computer when needed and close the ports when they are no longer needed.

Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, enable Universal Plug and Play (UPnP).

Add a Port Triggering Service

To add a port triggering service:

Any (the default) allows any computer on the Internet to use this service.
Single address restricts the service to a particular computer.

9. Select the service type, either TCP or UDP or TCP/UDP (both). If you are not sure, select TCP/UDP.10. In the Triggering Starting Port field, enter the beginning port number.11. In the Triggering Ending Port field, enter the ending port number.12. Enter the inbound connection port information in the Connection Type, Starting Port, and Ending Port fields.

13. Click the Apply button.The service is now in the Portmap table. You must enable port triggering before the cable modem router used port triggering for the service that you added. See the following section.

Application Example: Port Triggering for Internet Relay Chat

Some application servers, such as FTP and IRC servers, send replies to multiple port numbers. Using port triggering, you can tell the cable modem router to open more incoming ports when a particular outgoing port starts a session.

An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination port 6667. The IRC server not only responds to your originating source port, but also sends an “identify” message to your computer on port 113. Using port triggering, you can tell the cable modem router, “When you initiate a session with destination port 6667, you must also allow incoming traffic on port 113 to reach the originating computer.” The following sequence shows the effects of this port triggering rule:

1. You open an IRC client program to start a chat session on your computer.2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your cable modem router.3. Your cable modem router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your cable modem router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server.4. Based on your port triggering rule and the destination port number of 6667, your cable modem router creates another session entry to send any incoming port 113 traffic to your computer.5. The IRC server sends a return message to your cable modem router using the NAT-assigned source port (for example, port 33333) as the destination port. The IRC server also sends an “identify” message to your cable modem router with destination port 113.6. When your cable modem router receives the incoming message to destination port 33333, it checks its session table to see if a session is active for port number 33333. Finding an active session, the cable modem router restores the original address information replaced by NAT and sends this reply message to your computer.7. When your cable modem router receives the incoming message to destination port 113, it checks its session table and finds an active session for port 113 associated with your computer. The cable modem router replaces the message’s destination

IP address with your computer’s IP address and forwards the message to your computer.8. When you finish your chat session, your cable modem router eventually senses a period of inactivity in the communications. The cable modem router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers 33333 or 113.
