Static Routing

If the Router is connected to more than one network or there are multiple routers installed on your network, it may be necessary to set up static routes. The static routing function determines the path that data follows over your network before and after it passes through the Router. You can use static routing to allow different IP domain users to access the Internet through the Router.

Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use dynamic routing because it enables the Router to automatically adjust to physical changes in the network’s layout.

NOTE: Static routing is an advanced feature. Create these routes with care.

To create a static route entry, enter the following information:

Destination IP  Enter the network address of the remote LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP, while the last field should be 0.

Subnet Mask  Enter the subnet mask used on the destination LAN IP domain. For Class C IP domains, the subnet mask is 255.255.255.0.

Default Gateway  Enter the IP address of the router of the network, for which this static route is created. For example, if this network is connected to the local router’s LAN port through another router, use the WAN IP address of that router.

Hop Count  Enter the appropriate value (maximum is 15). This indicates the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as a computer or router.

Interface  Select the appropriate interface. The Interface tells you whether your network is on the LAN, WAN1, or WAN2/DMZ. If the gateway router is on a LAN port, then select LAN. If you’re connecting to another network through the Internet, select the appropriate WAN port option.

Click Add to List, and configure as many entries as you would like, up to a maximum of 30. To delete an entry, select it and click Delete selected IP.

Click Show Routing Table to see the details of your entries.

DHCP > Setup

The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP server option, all of the computers on your LAN must be set to obtain an IP address automatically from a DHCP server. (By default, Windows computers are set to obtain an IP automatically.)

If the Router’s DHCP server function is disabled, do one of the following:

•• Configure the IP address, subnet mask, and DNS settings of every computer on your network. (Make sure you do not assign the same IP address to different computers.)

•• Set up a stand-alone DHCP server with the Router as the default gateway.

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.
