Bandwidth Management

Overview

This appendix explains how to ensure Quality of Service (QoS) on Vonage Voice over Internet Protocol (VoIP) phone service. This example uses Vonage; however, similar instructions will apply to other VoIP services.

Creation of New Services

Create two new services, Vonage VoIP and Vonage 2.

1.Visit Vonage’s website at http://www.vonage.com. Find out the ports used for Vonage VoIP service.

2.Access the Router’s web-based utility. (Refer to “Chapter 4: Advanced Configuration” for details.)

3.Click the QoS tab.

4.On the Bandwidth Management screen, click Service Management.

QoS > Bandwidth Management

5.On the Service Management screen, enter a name, such as Vonage VoIP, in the Service Name field.

Bandwidth Management

Add Vonage VoIP Service

6.From the Protocol drop-down menu, select the protocol the VoIP service uses. For example, some VoIP devices use UDP.

7.Enter its SIP port range in the Port Range fields. For example, you can set the Port Range to 5060 to 5070 to make sure that all active ports are covered.

8.Click Add to List.

9.Add a second service. Enter a name, such as Vonage 2, in the Service Name field.

Add Vonage 2 Service

10.From the Protocol drop-down menu, select UDP.

11.Enter the RTP port range in the Port Range fields. These are required for both incoming and outgoing traffic. For example, you can set the Port Range to 10000 to 25000 to make sure that all active ports are covered.

12.Click Add to List.

13.Click Apply to save your changes.

RV042 specifications

The Linksys RV042 is a robust and versatile VPN router designed for small to medium-sized businesses, offering a wide array of features that cater to networking demands. Boasting dual WAN ports, the RV042 allows users to have two internet connections, providing load balancing and failover capabilities. This means that the router can automatically switch to a secondary Internet connection if the primary fails, ensuring uninterrupted connectivity crucial for business operations.

A key feature of the RV042 is its support for Virtual Private Networking (VPN). It can accommodate up to 50 VPN tunnels simultaneously, enabling secure remote access for employees who need to connect to the office network from various locations. The router supports both PPTP and L2TP/IPsec protocols, which provide a layer of encryption, ensuring that data remains secure while transmitted over public networks.

In terms of connectivity, the Linksys RV042 is equipped with four Ethernet ports, supporting speeds of up to 1 Gbps through its LAN (Local Area Network) connections. This allows for high-speed data transfer within the office premises, making it suitable for bandwidth-intensive applications such as video conferencing and large file transfers. Additionally, the router features an integrated firewall, which helps protect the network from external threats by filtering incoming and outgoing traffic.

The RV042 also excels in its Quality of Service (QoS) capabilities, which enable users to prioritize traffic for more critical applications. This is particularly beneficial in environments where multiple applications rely on the same bandwidth, allowing businesses to maintain optimal performance for essential tasks.

For businesses looking to manage their network more effectively, the RV042 offers a web-based interface that simplifies configuration and monitoring. The user-friendly dashboard allows administrators to track network usage, configure access controls, and set up security measures easily.

Overall, the Linksys RV042 VPN router stands out for its reliability, security features, dual WAN support, and ease of management. It is an excellent choice for organizations that require a secure, stable, and high-performance networking solution, enabling seamless connectivity and productivity in an increasingly digital business landscape.
