Reference Manual for the ProSafe VPN Firewall FVS318v3

When a PC accesses a resource by its descriptive name, it first contacts a DNS server to obtain the IP address of the resource. The PC sends the desired message using the IP address. Many large organizations, such as ISPs, maintain their own DNS servers and allow their customers to use the servers to look up addresses.

IP Configuration by DHCP

When an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each PC on the network can automatically obtain this configuration information. A device on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP server stores a list or pool of IP addresses, along with other information (such as gateway and DNS addresses) that it may assign to the other devices on the network. The FVS318v3 VPN Firewall has the capacity to act as a DHCP server.

The FVS318v3 VPN Firewall also functions as a DHCP client when connecting to the ISP. The firewall can automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway address if the ISP provides this information by DHCP.

Internet Security and Firewalls

When your LAN connects to the Internet through a router, an opportunity is created for outsiders to access or disrupt your network. A NAT router provides some protection because by the very nature of the process, the network behind the router is shielded from access by outsiders on the Internet. However, there are methods by which a determined hacker can possibly obtain information about your network or at the least can disrupt your Internet access. A greater degree of protection is provided by a firewall router.

The firewall offers advanced security features, including a stateful packet inspection (SPI) firewall and NAT (Network Address Translation), which helps protect the network from unauthorized access and external threats. Additionally, the FVS318v3 supports IPsec and SSL VPN protocols, providing secure remote access for employees working from home or on the go. With support for up to 15 SSL VPN clients and 20 IPsec VPN tunnels, it is suitable for businesses that require flexible and secure remote connectivity.

In terms of performance, the FVS318v3 boasts a high-speed gigabit throughput, ensuring fast data transmission and minimal latency. This is particularly important for businesses that rely on cloud-based applications, video conferencing, and other bandwidth-intensive activities. Furthermore, the device is equipped with advanced QoS (Quality of Service) features that allow administrators to prioritize traffic, ensuring that critical applications receive the bandwidth they need during peak usage times.

Another noteworthy characteristic of the NETGEAR FVS318v3 is its user-friendly interface, which simplifies network management and configuration. Administrators can easily set up policies, monitor traffic, and manage connected devices through an intuitive web-based interface. It also offers support for 802.1Q VLAN tagging, allowing for network segmentation and improved security management.

In conclusion, the NETGEAR FVS318v3 is a versatile and feature-rich solution that delivers exceptional security and reliability for businesses.
