These are the IP settings of the LAN interface for the TM-G5240. These settings may be referred to as Private settings. You may change the LAN IP address if needed. The LAN IP address is private to your internal network and cannot be seen on the Internet. The TM-G5240 has a built-in DHCP server. The TM-G5240 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked with the TM-G5240 are invisible to the outside world.

Page 48 T-Mobile TM-G5240 Wireless Router User Manual Version 0.7 041807 EXAMPLE 2 If you have an FTP server that you wanted Internet users to access by WAN port 2100 and only during the weekends, you would need to enable it as such. FTP server is on LAN computer 192.168.0.30. FTP uses port 21, TCP. These applications have difficulties working through NAT (Network Address Translation). Special Applications makes some of these applications work with the TM-G5240. You may define a single port or a range of ports. The TM-G5240 can be setup to deny internal computers by their IP or MAC addresses. The TM-G5240 can also block users from accessing restricted web sites. A URL is a specially formatted text string that defines a location on the Internet. If any part of the URL contains the blocked word, the site will not be accessible and the web page will not display. To use this feature, enter the text string to be blocked and click Apply. The text to be blocked will appear in the list. Domain blocking will deny all requests to a specific domain such as http and ftp. It can also allow computers to access specific sites and deny all other sites. A URL is a specifically formatted text string that defines a location on the internet. It works in the same way as IP Filters with additional settings. You can create more detailed access rules for the TM-G5240. When virtual services are created and enabled, it will also display in Firewall Rules. Firewall Rules contain all network firewall rules pertaining to IP (Internet Protocol). It allows a computer to be exposed to the Internet. This feature is useful for gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless network adapters. Auto is the default setting.

Note: High network traffic areas should use the shorter preamble type. There are two accounts that can access the wireless router’s Web-Management interface. They are admin and user. User can only view the settings but cannot make any changes. NTP synchronizes computer clock times in a network of computers. The saved file or any other saved setting file can be loaded back on the wireless router. To reload a system settings file, click on Browse to browse the local hard drive and locate the system file to be used. You may also reset the wireless router back to factory settings by clicking on Restore. Make sure the firmware you want to use is on the local hard drive of the computer. Click on Browse to browse the local hard drive and locate the firmware to be used for the update. Please check the D-Link support site for firmware updates at You can download firmware upgrades to your hard drive from the D-Link support site. Select Disabled to Enable. Users who have a Dynamic DNS account may use this feature. This is a useful feature since many computers do not use a static IP address. Through the graphical user interface (GUI), Cable Tester can be used to remotely diagnose and report cable faults such as opens, shorts, swaps, and impedance mismatch. It enables users to easily troubleshoot their cable connections. It is a process where the security settings of the TM-G5240 get transmitted to the phone. It will display the LAN, WAN, and MAC address information.If your WAN connection is set up for a Dynamic IP address then a Release button and a Renew button will be displayed. Use Release to disconnect from your ISP and use Renew to connect to your ISP. If the device is rebooted, the logs are automatically cleared. You may save the log files under Log Settings. Here you can view the amount of packets that pass through the TM-G5240 on both the WAN and the LAN ports. The traffic counter will reset if the device is rebooted.

This table also displays the connection time and MAC address of the connected wireless client. Click Help at any time for more information.

For more information, or to change your cookie settings, learn more about cookies If you have a D-LINK router that is not one of the above models, you are advised to still update your firmware, as it is not currently known if other models are affected.

These connections can be via a network cable (also called an Ethernet cable) or through a wireless connection. Routers can be configured to allow or disallow certain types of traffic, set your wireless password, control how computers can connect to the internet, and many other options. Configurations are performed through an administrator website, which is normally protected by a username and password. An example image of a router is shown below, but routers come in a very wide range of designs. The discovered vulnerability could allow anyone from the internet to access your administrator website without the password by sending a specific phrase to the router. The phrase was discovered by reverse engineering —examining the contents of the code on the router. Such backdoors can often be malicious, for example a disgruntled employee inserting the vulnerability so that they may later exploit it. However this particular backdoor appears to be for testing purposes but should have been removed before the router was sold. There does not appear to be any evidence of malicious intent behind this backdoor, however it can still be exploited by people with malicious intent. To address Joel’s Backdoor, D-LINK have provided a firmware update that addresses the issue. A bad firmware update can render your device unusable and, in the case of a router, can disconnect all of your computers from the internet. Use the instructions there to find your model number and hardware revision before applying the firmware update. Ensure you download the correct firmware for your model of D-LINK router. This can vary from device to device, and the instructions need to be followed exactly. You will need to access your administrator panel to perform the update. By default, the address you can use to access this via a browser is, and will take you to your router’s administrative panel, however your configuration may be different. If you are unsure of a step, seek technical advice.

This step is recommended for most routers, not just D-LINK models. The instructions below are given for common D-LINK routers and may vary between brands and models. On D-LINK routers, navigate to your administrative panel (by default ) and click “Tools”. Then find the option for “Remote Management” and click “Disabled”. Then click the “Apply” button to confirm the setting. If a vulnerability similar to the one explained in this alert was to be found in the future (or in a different router), disabling “Remote Management” would stop people from the internet being able to exploit it. This article also contains more information on how to disable Remote Management to secure your router.While the vulnerability explained in this alert by-passes the router's password, it is still important to set a strong password to prohibit password guessing. Everyone's circumstances are different. If you require specific advice you should contact your local technical support provider.
