    Introduction 1.1 Introducing the BEC 7300N Thank you for purchasing the BEC 7300N Router. Your new router is an all-in-one unit that combines an ADSL modem, ADSL2/2+ router and Ethernet network switch to provide everything you need to get the machines on your network connected to the Internet over an ADSL broadband connection.
  • Page 5 The BEC 7300N provides two levels of security support. First, it masks LAN IP addresses making them invisible to outside users on the Internet, so it is much more difficult for a hacker to target a machine on your network. Second, it can block and redirect certain ports to limit the services that outside users can access.

    Ethernet cables. EWAN Besides using ADSL to get connected to the Internet, BEC 7300N offers its Ethernet port 1 as a WAN port to be used to connect to Cable Modems, VDSL and fibre optic lines. This alternative, yet faster method to connect to the internet will provide users more flexibility to get online.
  • Page 7 DDNS service such as http://www.dyndns.org/. PPP over Ethernet (PPPoE) The BEC 7300N provides an embedded PPPoE client function to establish a connection. You get greater access speed without changing the operation concept, while sharing the same ISP account and paying for one access account. No PPPoE client software is required for the local computer.
  • Page 8 QoS gives you full control over which types of outgoing data traffic should be given priority by the router, ensuring important data like gaming packets, customer information, or management information move through the router ay lightning speed, even under heavy load.

    Keep the number of walls and ceilings between the BEC 7300N and other network devices to a minimum - each wall or ceiling can reduce your BEC 7300N wireless product’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

  • Page 11: Important Notes

    Do not use the same power source for the BEC 7300N as other equipment. Do not open or repair the case yourself. If the BEC 7300N is too Warning hot, turn off the power immediately and have it repaired at a qualified service center.

  • Page 74: Time Zone

    5.3.3.1 Time Zone The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server outside your network. Choose your local time zone, click Enable and click the Apply button. After a successful connection to the Internet, the router retrieves the correct local time from the SNTP server you have specified.
  • Page 75 5.3.3.2 Firmware Upgrade Your router’s “firmware” is the software that allows it to operate and provides all its functionality. Think of your router as a dedicated computer, and the firmware as the software it runs. Over time this software may be improved and modified. Your router allows you to upgrade the software it runs to take advantage of these changes.
  • Page 76 5.3.3.3 Backup / Restore These functions allow you to save and backup your router’s current settings to a file on your PC, or to restore a previously saved backup. This is useful if you wish to experiment with different settings, knowing that you have a backup handy in the case of any mistakes. It is advisable to backup your router’s settings before making any significant changes to your router’s configuration.

This natural firewall is on when the NAT function is enabled. When using Virtual Servers (port mapping) your PCs are exposed to the ports specified opened in your firewall packet filter settings.
  • Page 80 A detailed explanation of each of the following five items appears in the Firewall section below: Packet Filter, MAC Address Filter, Intrusion detection, Block WAN PING and URL Filter. 5.3.4.1 Packet Filter Packet filtering enables you to configure your router to block specified internal/external users (IP address) from Internet access, or you can disable specific service requests (Port number) to /from Internet.

Internal IP Address / External IP Address: This is the Address-Filter used to allow or block traffic to/from particular IP address(es).
  • Page 82 If the DHCP server option is enabled, you must be very careful in assigning IP addresses of a filtered private IP range to avoid conflicts because you do not know which PC in the LAN is assigned which IP address. The easiest and safest way is that the filtered IP address is assigned to a specific PC that is not allowed to access an outside resource such as the Internet.
