    Chip (SoC) solution, NP25G supports high-speed data transmission of up to 54Mbps. NetPassage NP25G combines 3 devices into one box. It works as a Wireless Access Point, which allows you to connect Wireless B/G devices to the network. It also has a 4-port full-duplex 10/100Mbps switch which connects your wired Ethernet devices directly to 4 PCs or to additional hubs and switches to create a larger network.

  • Page 20: Security Features

    Security Features WPA-PSK and 64/128-bit WEP encryption support for wireless security The router uses a private key encryption known as Wired Equivalent Privacy protocol with key lengths of either 64-bit or 128- bit, so that data communication in your wireless network can be protected.
  • Page 21 Built-in “NAT” firewall As the router handles the incoming and outgoing traffic of data packets between the internal and external network, it checks whether incoming WAN packets are legitimate replies to requests from LAN users before allowing them to pass into the LAN. This checking provides effective firewall protection because rogue Internet packets will be automatically discarded.
  • Page 22 Stateful Packet Inspection (SPI) firewall More than just a “NAT” firewall, there is a powerful Stateful Packet Inspection (SPI) firewall in the router. Stateful inspection compares certain key parts of the packet to a database of trusted information. SPI Firewall is unlike the normal firewall that only checks the headers of the packets, it also scrutinizes the contents of the packets, ensuring the integrity of the packets.
  • Page 23 Internet Access Policies: Time-based Management, URL filtering, Packet filtering To complement the powerful firewall technologies incorporated into the router product, you can use the comprehensive set of security management features to regulate the types of Internet access permitted. You may set up time-based access policies and block objectionable websites from children, or even set up packet filtering rules to control the transmission of TCP, UDP packets for different ports.

  • Page 106 4. Click on the Add button and you will be able to define the details of your Packet Filter Rule from the screen on the right. 4a). Enter Rule Name for this new packet filtering rule. For example, BlockCS 4b). Enter MAC Address for this new packet filtering rule.
  • Page 107 define (From) which port (To) which port, your rule applies. Single TCP port Here, you need only specify the source port in the (From) field. IP port You may here, leave both, the (From) as well as the (To) fields, blank. Here, the rule will apply to all ports.
  • Page 108 Filtering Configuration table will then be updated. 5. In this example, let us say we would like to block an application called CS from all PCs (any IP address within the network) from Monday to Friday 7am to 6pm, and this application is using the port number 27015.

  • Page 110: Configure Firewall

    Configure Firewall More than just a “NAT” firewall, there is a powerful Stateful Packet Inspection (SPI) firewall option that can be activated on the router. Stateful inspection compares certain key parts of the packet to a database of trusted information before allowing it through. Common hacker attacks like IP Spoofing, Port Scanning, Ping of Death and SynFlood can be easily thwarted with the router’s SPI firewall.
  • Page 111 Rule Name Enter a unique name to identify this firewall rule. Disposition This parameter determines whether the packets obeying Policy the rule should be accepted or denied by the firewall. Choose between Accept and Deny. Protocols Users are allowed to select the type of data packet from: TCP, UDP, ICMP, IGMP or ALL.
  • Page 112 IGMP Types This IP protocol is used to establish host memberships in particular multicast groups on a single network. The mechanisms of the protocol allow a host to inform its local router, using Host Membership Reports. Host Information that is from the Membership IGMP data packet.

  • Page 114: View Firewall Logs

    View Firewall Logs When the router’s SPI firewall is in operation, valuable traffic patterns in your network will be captured and stored into the Firewall Logs. From these logs, you can extract detailed information about the type of data traffic, the time, the source and destination address/port as well as the action taken by the SPI firewall.

    Administer the System Use the SYSTEM TOOLS Menu Use the Ping Utility This feature lets you determine whether your router can communicate (ping) with another network host. 1. Select Ping Utility under the SYSTEM TOOLS command menu. 2. Enter the IP address of the target host where the target host you want the router to ping to.

  • Page 116: Set The Time

    Set the Time The router is specially designed with Simple Network Time Protocol (SNTP) compatibility so that the router’s clock can be synchronized with that of the managing computer. The router’s clock is an important feature that affects all the time-based functions. It is a simple 2 steps process to ensure that the router’s clock is synchronized.

    Upgrade the Firmware Significantly, the router is built with upgradability in mind. You can keep your router updated with the latest capabilities by means of a simple firmware upgrade obtainable from your vendor. 1. Select Firmware Upgrade under the SYSTEM TOOLS command menu. The screen displays a notice to inform you that the services being used will be terminated.

  • Page 118: Settings Profile

    Settings Profile A useful feature is built into the router allowing you to save configuration profiles, especially the painstakingly crafted firewall security rules, and the intricate IP and Port settings of your Virtual Servers that effect a host of network applications. You may choose to save the configuration profile onto the router as a backup onto your hard disk drive.

  • Page 119: Reboot The System

    Reboot the System This feature serves an important function so that the router settings will become effective. 1. Select Reboot Router under the SYSTEM TOOLS command menu. 2. The router will prompt you to confirm your decision before executing a reboot. Hit the Reboot button again when you are ready.
