NAT Configuration

NAT

Enable/disable NAT (Network Address Translation). The default is Enable.

If NAT is enabled:

Your LAN can use one set of IP addresses for internal traffic and a second set of addresses for external traffic. In other words, the router with NAT does the simple IP routing between the LAN interface and the WAN interface.

Your internal addresses are shielded from the public Internet.

If NAT is disabled:

The router functions without performing any address translation on the packets passing through it.

Masquerading of packets originating from the LAN is disabled.

Address translation of packets arriving from the WAN is also disabled.

Any DNAT Configuration previously setup in the DNAT Configuration screen is disabled. This prevents the user from adding any DNAT rules, which if allowed would defeat the purpose of enabling Routing.

Note: For routing to take effect, the configuration must be saved after enabling it. It won’t be effective on the fly at runtime.

RJ-9, RJ-45 specifications

Multi-Tech Systems offers a range of communication solutions, prominently featuring the RJ-45 and RJ-9 connectors that are crucial in networking and telecommunications. These connectors are foundational to many applications, enabling efficient data transfer and ensuring reliable voice communications.

The RJ-45 connector is primarily used in Ethernet networks. It features eight pins and is designed for high-speed data transmission, making it the standard for wired local area networks (LANs). This connector supports various Ethernet standards including Fast Ethernet (100BASE-T), Gigabit Ethernet (1000BASE-T), and even 10 Gigabit Ethernet (10GBASE-T). An essential characteristic of the RJ-45 is its versatility, as it can be used with both straight-through and crossover cable configurations. This flexibility allows for straightforward connectivity between devices such as computers, routers, and switches.

Multi-Tech Systems employs advanced technology in their RJ-45 connectors, including support for Power over Ethernet (PoE). This innovation permits electrical power and data to be transmitted over the same cable, simplifying installations and reducing the need for additional wiring. The robust design of these connectors ensures durability and minimizes signal interference, thereby maximizing data integrity during transmission.

On the other hand, the RJ-9 connector, also known as the RJ-9 or RJ-10 connector, is typically used in telephone and headset applications. Characterized by its smaller size and four or six pins, the RJ-9 is optimized for voice frequency communication. It connects devices such as telephones, headsets, and other VoIP equipment, delivering clear audio quality that is essential for effective communication.

One standout feature of the RJ-9 connector is its ability to provide superior noise resistance, making it ideal for environments with significant electromagnetic interference. Multi-Tech Systems' RJ-9 connectors are designed for ease of use, allowing quick and simple connections. These connectors can often be found in various telephony devices, ensuring that they remain a staple in personal, commercial, and industrial communication systems.

In conclusion, Multi-Tech Systems continues to lead in the provision of reliable RJ-45 and RJ-9 connectors, integrating innovative technologies that enhance performance in data and voice communication. Whether in a high-speed networking environment or in everyday telephony applications, these connectors deliver the functionality and quality demanded by modern users. Their design and engineering reflect a commitment to excellence, helping users stay connected in an increasingly digital world.
