  • Page 62: Pptp Connection

    By implementing PPPoE directly on the NBG318S (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG318S does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

    The subnet mask specifies the network number portion of an IP address. Your NBG318S will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the NBG318S unless you are instructed to do otherwise.

  • Page 66: Wan Ip And Dns Server Address Assignment

    The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG318S uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server.

  • Page 67: Wan Mac Address

    This screen allows users to configure the WAN port's MAC address by either using the NBG318S’s MAC address, copying the MAC address from a computer on your LAN or manually entering a MAC address. Once it is successfully configured, the address will be copied to the "rom"...

  • Page 68: Connection Wizard: Step 4: Bandwidth Management

    Bandwidth management allows you to control the amount of bandwidth going out through the NBG318S’s WAN, LAN or WLAN port and prioritize the distribution of the bandwidth according to the traffic type. This helps keep one service from using all of the available bandwidth and shutting out other users.

    When you select WPA2 or WPA2-PSK in your NBG318S, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA Compatible option in the NBG318S.

  • Page 79: Wmm Qos

    The NBG318S uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag or DSCP information in each packet’s header. The NBG318S automatically determines the priority to use for an individual traffic stream.

  • Page 80: No Security

    Select No Security to allow wireless stations to communicate with the access points without any data encryption. If you do not enable any wireless security on your NBG318S, your network is accessible to any wireless networking device that is within range.
