Bridge mode Firewall Configuration Settings

Firewall functionality on any router interface can be enabled using the "Enable Firewall" option. Router Firewall rules can be configured, enabled or disabled while using Firewall configuration window which is opened with the "Configure" button.

Firewall entries can be specified by using the following criteria:

Interface the interface (WLAN, LAN or PPP) where filtering of the incoming/passing-through packets is processed;

IP Type sets which particular L3 protocol type (ICMP, TCP, UDP, P2P) should be filtered; Source IP/mask is the source IP of the packet (specified within the packet header), usually it is

the IP of the host system which sends the packets;

Source Port is the source port of the TCP/UDP packet (specified within the packet header), usually it is the port of the host system application which sends the packets;

Destination IP/mask is the destination IP of the packet (specified within the packet header), usually it is the IP of the system which the packet is addressed to;

Destination Port is the destination port of the TCP/UDP packet (specified within the packet header), usually it is the port of the host system application which the packet is addressed to.

Comments is the informal field for the comment of the particular firewall entry. Few words about the particular firewall entry purpose are saved there usually.

On flag enables or disables the effect of the particular firewall entry. All the added firewall entries are saved in system configuration file, however only the enabled firewall entries will be active during device operation.

New entries in Firewall can be saved by activating Apply Setting and Save Changes button or discarded by activating Cancel button in the Firewall configuration window.

All the active firewall entries are stored in the FIREWALL chain of the iptables filter table, while the device is operating in Router mode.

PPPoE: Point-to-Point Protocol over Ethernet (PPPoE) is a virtual private and secure connection between two systems which enables encapsulated data transport. It is commonly used as the medium for subscribers to connect to Internet Service Providers.

Select the IP Address option PPPoE to configure a PPPoE tunnel in order to connect to an ISP. Only the external network interface can be configured as PPPoE client as all the traffic will be sent via this tunnel. The IP address, Default gateway IP and DNS server IP address will be obtained from the PPPoE server after PPPoE connection is established. Broadcast address is used for the PPPoE server discovery and tunnel establishment.

Valid authorization credentials are required for the PPPoE connection:

PPPoE Username – username to connect to the server (must match the configured on the PPPoE server);

Password – password to connect to the server (must match the configured on the PPPoE server);

PPPoE MTU/MRU – the size (in bytes) of the Maximum Transmission Unit (MTU) and Maximum Receive Unit (MRU) used for the data encapsulation while transferring it through the PPP tunnel;

802.11N specifications

Compex Systems 802.11N solutions are designed to provide high-performance wireless networking, catering to the growing demand for faster and more reliable connectivity in various applications. The 802.11N standard, also known as Wi-Fi 4, significantly enhances the capabilities of previous Wi-Fi standards by utilizing advanced technologies and features.

One of the key characteristics of Compex Systems 802.11N products is their support for Multiple Input Multiple Output (MIMO) technology. MIMO allows the transmission of multiple data streams simultaneously, effectively improving throughput and range. This is especially useful in environments with high user density or physical obstructions, as it enhances the signal quality and minimizes interference.

Another significant feature is the use of Channel Bonding, which combines two adjacent channels to double the data rate. This capability enables users to experience higher speeds, typically reaching up to 600 Mbps under optimal conditions. The dual-band operation, supporting both 2.4 GHz and 5 GHz frequencies, further enhances flexibility and performance. The 2.4 GHz band offers broader coverage, while the 5 GHz band provides faster speeds with less congestion.

Compex Systems also incorporates advanced security protocols in their 802.11N solutions. With support for WPA2 encryption and robust authentication methods, users can ensure that their connections remain secure, protecting sensitive data from potential threats.

Quality of Service (QoS) is another critical feature, allowing network administrators to prioritize traffic according to application needs. This ensures that bandwidth-intensive applications, such as video streaming and online gaming, receive the necessary resources for optimal performance, even in a crowded network environment.

Designed for versatility, Compex Systems 802.11N devices can be employed in various scenarios, including enterprise, education, healthcare, and hospitality sectors. Their compact and durable designs make them suitable for deployment in both indoor and outdoor settings.

Overall, Compex Systems 802.11N solutions offer a comprehensive set of features and technologies aimed at providing robust, high-speed wireless connectivity. With MIMO, Channel Bonding, dual-band support, enhanced security, and QoS capabilities, these systems are well-suited to meet the demands of modern wireless networking environments.
