Beacon Interval  Enter a value between 1 and 65,535 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Valet to synchronize the wireless network. The default value is 100..

DTIM Interval  This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Valet has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1..

Fragmentation Threshold  This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346..

RTS Threshold  Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Valet sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2347..

Security > Firewall

The Firewall screen is used to configure a firewall that can filter out various types of unwanted traffic on the Valet’s local network. 

Security > Firewall

Firewall

SPI Firewall Protection  To use firewall protection, keep the default selection, Enabled. To turn off firewall protection, select Disabled..

Internet Filter

Filter Anonymous Internet Requests  This feature makes it more difficult for outside users to work their way into your network. This feature is selected by default.  Deselect the feature to allow anonymous Internet requests..

Filter Multicast  Multicasting allows for multiple transmissions to specific recipients at the same time.  If multicasting is permitted, then the Valet will allow IP multicast packets to be forwarded to the appropriate computers. Select this feature to filter multicasting. This feature is not selected by default..

Filter Internet NAT Redirection  This feature uses port forwarding to block access to local servers from local networked computers. Select this feature to filter Internet NAT redirection. It is not selected by default..

Filter IDENT (Port 113)  This feature keeps port 113 from being scanned by devices outside of your local network. This feature is selected by default. Deselect this feature to disable it..

Web Filter

Proxy  Use of WAN proxy servers may compromise the Gateway’s security. Denying Proxy will disable access to any WAN proxy servers. Select this feature to enable proxy filtering. Deselect the feature to allow proxy access..

Java  Java is a programming language for websites. If you deny Java, you run the risk of not having access to Internet sites created using this programming language.  Select this feature to enable Java filtering. Deselect the feature to allow Java usage..

ActiveX  ActiveX is a programming language for websites. If you deny ActiveX, you run the risk of not having access to Internet sites created using this programming language. Select this feature to enable ActiveX filtering. Deselect the feature to allow ActiveX usage..

Cookies  A cookie is data stored on your computer and used by Internet sites when you interact with them. Select this feature to filter cookies. Deselect the feature to allow cookie usage..

M10, M20 specifications

Cisco Systems has long been a leader in networking solutions, and their M20 and M10 routers exemplify the company’s commitment to providing powerful and efficient connectivity solutions for businesses of all sizes. These routers are designed to meet the demanding needs of enterprises, offering advanced features, robust performance, and a variety of technologies to ensure reliable network operation.

The Cisco M20 router is built for scalability and high performance. It supports a wide range of applications and workloads, making it ideal for medium to large enterprises. One of its main features is its ability to handle multiple service protocols, including MPLS and BGP, which enhances routing capabilities and optimizes traffic flow. Additionally, the M20 is designed with high availability in mind, featuring redundancy options that minimize downtime and ensure continuous service.

On the other hand, the Cisco M10 router is tailored for smaller network environments while still delivering impressive performance. Its compact design makes it an excellent fit for branch offices or remote sites. This model includes integrated security features, such as advanced firewall capabilities and Intrusion Prevention Systems (IPS), providing a multi-layered defense against cyber threats.

Both routers leverage Cisco’s advanced IOS software platform, which provides a user-friendly interface for configuration, monitoring, and management. This allows IT administrators to quickly deploy and manage network services with ease. The routers also support Cisco's extensive range of analytics and monitoring tools, enabling organizations to gain deeper insights into their network performance and user behavior.

In terms of connectivity, the M20 and M10 support a multitude of ports and interfaces, allowing for seamless integration with existing network infrastructures. They also feature support for IPv6, ensuring future-proofing for businesses as the Internet continues to evolve.

The M20 supports various high-speed WAN connections, catering to enterprises with heavy data traffic demands. Conversely, the M10, while providing sufficient capabilities for smaller data loads, still offers the flexibility necessary for smaller networks to thrive.

In summary, Cisco’s M20 and M10 routers present businesses with powerful networking solutions that combine advanced features, robust technology, and adaptability to meet the diverse needs of modern enterprises. With their focus on performance, security, and scalability, these routers are poised to help organizations navigate the complexities of today’s digital landscape effectively.
