• Dual WAN with automatic failover and load balancing: The RV042 provides two independent Internet connections so you can keep your business online if one link goes down. It intelligently failovers between connections and can balance traffic across both WAN ports to optimize bandwidth, improve reliability, and minimize downtime for critical applications and services.
• Four-port Fast Ethernet LAN for shared connectivity: Four 10/100 Ethernet LAN ports let you connect multiple computers, printers, IP phones, and other network devices in your office. This compact, all-in-one router consolidates routing, firewalling, and VPN in a single device, simplifying deployment and maintenance for small teams.
• Robust VPN capabilities for secure remote access and site-to-site connections: The RV042 supports IPsec VPN tunnels to securely connect remote workers and branch offices. Whether you need secure point-to-point links between locations or reliable remote access for offsite employees, this router provides encryption and management features to protect sensitive data in transit.
• Comprehensive security and traffic management: Built-in Stateful Packet Inspection firewall, NAT, VPN pass-through, and Denial-of-Service protection help shield your network from threats. QoS and traffic prioritization ensure business-critical apps—VoIP, video conferencing, and ERP traffic—get the bandwidth they need when it matters most.
• Easy setup, management, and compatibility: A user-friendly web-based interface and setup wizards simplify deployment. The RV042 integrates with standard networking gear, supports remote management, and provides straightforward configuration for VPNs, firewall rules, and bandwidth policies—making it ideal for small businesses without a dedicated IT staff.

How to install Cisco RV042 4-Port Fast Ethernet VPN Router-Dual WAN

• Unpack the Cisco RV042 and verify that you have the router, power adapter, Ethernet cables, and any included mounting hardware. Place the device in a well-ventilated area near your modem or primary gateway and near enough to your workstations for easy cabling.
• Connect the WAN ports to your Internet sources. If you have two active Internet connections, plug one modem into each WAN port. Use separate cables to maintain true dual-WAN functionality and enable failover and load balancing.
• Connect your local devices to the four LAN ports on the RV042 and connect the power adapter to power on the device. Wait for the device to boot; the status indicators should show normal activity when ready.
• Access the router’s web-based management interface by opening a browser and entering the default IP address (commonly 192.168.1.1). Log in with the default credentials provided in the user manual, then follow the Quick Setup or Advanced Setup wizard to configure WAN, LAN, and security settings.
• Configure WAN settings for each Internet connection (DHCP or static IP, depending on your ISP). Enable dual WAN with failover or load balancing as required, and set a desired failover threshold and monitoring checks to ensure automatic switchover when a link fails.
• Set up your local network parameters (LAN IP range, DHCP scope, and DNS options). Create any necessary VLANs or subnets if your office requires segmentation for security or performance reasons.
• Configure VPN settings. Create IPsec VPN tunnels for site-to-site connections or remote access as needed. Enter peer IPs, shared secrets or certificates, encryption methods, and pre-shared keys. Test the VPN connections to confirm successful establishment and traffic routing.
• Define QoS policies to prioritize critical traffic such as VoIP and conferencing. Save your configuration and perform a full network test to ensure that failover, VPN, and traffic prioritization work as intended.
• Apply security rules and firewall policies. Consider creating rules that restrict inbound connections, define VPN pass-through allowances, and ensure that only trusted services are exposed to the Internet. Regularly update firmware to keep the device secure and protected.
• Document your settings for future reference and set up regular monitoring of WAN status, VPN connections, and traffic patterns. Periodic reviews help keep your network performing at its best as your business grows.

Frequently asked questions

• What is dual WAN and why do I need it? Dual WAN provides two Internet connections for redundancy and load balancing. If one connection experiences an outage or degradation, the RV042 can automatically switch to the other connection, minimizing downtime and maintaining productivity for your team.
• Can the RV042 support remote workers and branch offices? Yes. The router supports IPsec VPN tunnels for secure remote access and site-to-site connections, allowing remote employees and multiple locations to connect to your main office with encrypted communications and centralized policy management.
• Does the RV042 include a firewall and traffic management? The RV042 features a Stateful Packet Inspection firewall, NAT, and QoS (Quality of Service) to prioritize business-critical applications. This helps protect your network from threats while ensuring that essential services receive the bandwidth they need.
• Is setup difficult for small businesses without dedicated IT staff? No. The RV042 offers a user-friendly web-based interface and setup wizards to guide you through WAN configuration, VPN setup, firewall rules, and QoS settings. With clear documentation and straightforward steps, most small businesses can deploy and manage the router effectively.
• How does VPN performance vary with dual WAN? VPN performance is influenced by the Internet connections and the configured bandwidth policies. The RV042 enables you to allocate bandwidth and prioritize VPN-related traffic to maintain secure, reliable connections for remote workers and partner sites while balancing overall network load.
