86CHAPTER 5: ROUTER CONFIGURATION

3Com recommends that you leave this feature disabled for maximum security.

■Allow PING from the Internet - PING is a utility, which is used to determine whether a device is active at the specified IP address. PING is normally used to test the physical connection between two devices, to ensure that everything is working correctly.

By default the Router has PING disabled in order to make the device more difficult to find on the Internet and less prone to attack.

Check on the check box to enable this feature, and then select Save.

3Com recommends that you leave this feature disabled for maximum security.

■Disable NAT - Network Address Translation (NAT) is the method by which the Router shares the single IP address assigned by your ISP with the computers on the network. Only disable NAT if your ISP assigns you multiple IP addresses or you need NAT disabled for an advanced system configuration. If you have a single IP address and your turn NAT off, the computers on your network will not be able to access the Internet. Other problems may also occur.

Check on the check box to disable NAT, and then select Save.

3Com recommends that you leave this feature enabled for maximum security.

Enabling Remote Administration

It is possible to administer the Router remotely. Select one of the following options for remote administration:

■Disable Remote Administration - This option is set as default.

■Enable administration from a single Internet Host - Only the specified Host IP Address can manage the Router. Any other users will be rejected.

■Enable administration from a whole subnet - This option allows a number of users within the specified Host Network Address and Subnet Mask to administer the Router.

■Enable administration from any Internet Host - This option allows any host to access the administration pages.

WL-537, WL-537S specifications

The 3Com WL-537S and WL-537 are advanced wireless access points designed to enhance networking capabilities in both enterprise and residential settings. These models are part of 3Com's effort to provide reliable connectivity, improved performance, and robust security.

The WL-537S is particularly notable for its versatility and extended range. It supports both 2.4 GHz and 5 GHz frequencies, allowing users to choose between a wider range or higher speed depending on their needs. With 802.11n technology, it offers significant improvements in data rates and reach compared to earlier standards. This dual-band functionality enables users to run multiple applications simultaneously without sacrificing performance. The access point can handle higher traffic volumes efficiently, making it ideal for environments with many users.

One of the standout features of the WL-537S is its integrated Power over Ethernet (PoE) capability, which simplifies installation by allowing the device to receive power and data over a single Ethernet cable. This is particularly useful in locations where power outlets are limited or hard to reach. Additionally, the access point’s lightweight, compact design allows for easy mounting on ceilings or walls, providing versatility in deployment.

Both models offer advanced security mechanisms, essential for protecting sensitive information in a network. They come equipped with multiple encryption protocols, including WPA2 and WPA3, ensuring that data transmission remains secure. Moreover, with features like Remote Authentication Dial-In User Service (RADIUS) support and VLAN tagging, organizations can implement fine-grained control over user access and data traffic.

Additionally, the WL-537 and WL-537S support several network management features, including a web-based interface for easy configuration and monitoring. This feature is particularly useful for IT administrators who need to manage settings remotely or troubleshoot issues.

Dynamic load balancing is another key characteristic of these access points. By distributing the network load evenly among connected devices, the WL-537S and WL-537 ensure that no single device gets overwhelmed, thus maintaining optimal performance across the network.

In conclusion, the 3Com WL-537S and WL-537 access points combine robust technology, security features, and flexibility to meet the demands of modern networking. With their dual-band capabilities, PoE integration, and management features, they provide an ideal solution for users looking to enhance their wireless network experience.
