  • Page 43: Configuring For Internet Access

    Configuring for Internet Access Menu 4 of the SMT allows you to configure Internet access on one screen. Before you configure your Prestige for Internet access, you need to collect the following information from your ISP (Internet Service Provider). IP address of the ISP’s gateway (optional). Login name (optional).

  • Page 44: Ip Addresses And The Internet

    IP Addresses and the Internet Conventionally, the Internet (with a capital I) refers the large-scale interconnected networks across the world that was originally developed by the US Department of Defense. The Internet uses exclusively the TCP/IP suite of protocols. The term “internet” (lower case i), however, refers to any interconnected networks using any protocol.

  • Page 45: Internet Access Configuration

    LLOCATION FOR ANAGEMENT OF Once you have determined the IP address range for your local network, you may want to use DHCP (Dynamic Host Configuration Protocol) to assign addresses to individual hosts on the network, as an alternative to manually configuring each host’s IP settings. See the TCP/IP Ethernet Setup and DHCP section on page 26 for more information about DHCP.

    3. ISP IP Addr - Enter the IP Address of the remote gateway at the ISP’s site. If you do not have this data, just leave it blank. 4. My Login Name - Enter the login name provided by your ISP. 5.
  • Page 47 This feature may also be used to connect to TCP/IP remote nodes other than Internet Service Providers. For example this feature can be used to simplify the allocation of IP addresses when connecting branch offices to the corporate network. The IP address for the Single User Account can be either fixed or dynamically assigned by the ISP (or other remote node).

  • Page 48: Configuration For Single User Account

    UDP and TCP datagrams can be routed. In addition, ICMP echo can also be routed. The figure below shows an example of a small office connected to the Internet via a Single User Account using your Prestige. Note that if you enable the Single User Account feature, your local IP address MUST be selected from the list of IP addresses for private networks as defined by the IANA.

  • Page 79: Filter Configuration

    Filter Configuration About Filtering Your Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call over the ISDN line. There are two types of filters involved: incoming data filters and outgoing data filters. Data filters screen the data to determine if the packet should be allowed to pass.

  • Page 80: Prestige's Filter Structure

    Prestige’s Filter Structure You can configure up to twelve filter sets with six rules in each set. Therefore, your Prestige allows you to customize up to 72 filter rules (12 x 6). When implementing these filter sets, you can link up to four of the filter sets together to screen the data packet.

    The Simple Network Management Protocol (SNMP) is a protocol governing network management and the monitoring of network devices and their functions. The Prestige 128L supports the utilization of SNMP to regulate the communication that occurs between the manager station and the agent stations in a network. Basically, your Prestige, when connected to the LAN, acts as an agent station.
