Connecting your LAN to the Internet

TCP/IP Configuration (LAN) - 2
Routing Tab
Route Type DEFAULT Net
Destination 24
Router 24.114.210.129 24.114.210.129
Metric 1 1
Subnet Mask 255.0.0.0
IP Forwarding Checked

  1. You need both a DEFAULT entry and NET entry for proper resolution of both internal LAN messages and outgoing messages.

  2. Fill in the Router fields with the information you received from your Internet Provider.

  3. Fill in that portion of the Router IP and Submask that is displayed in the table--only the upper octets are required.

  4. Note: The Gateway must have the IP Forwarding box checked.

    TCP/IP Configuration (LAN) - 3
    Hostname Tab
    LAN Name Resolution Services
        Machine's HostName WALTER-DESKTOP
    Local Domain Name ktchnr1.on.wave.home.com
    Nameserver Addresses 24.2.9.33
    24.2.9.34
    Configure Name Resolution Services
       IP Address 209.87.233.53
    Hostname time.chu.nrc.ca
    Look through HOSTS lists... Leave unchecked.

  5. This section provides the information necessary to translate Hostnames and other alphanumeric Internet names into the corresponding IP addresses. It is like a micro-nameserver.

  6. The HostName can be any name, up to 16 characters, unique to this network. Use a name that readily identifies this particular computer.

  7. For the Local Domain Name and Name Server Addresses, once again use the information provided by your Internet Provider.

  8. Nothing is actually required under Name Resolution Services (Hostnames, p. 2). Anything you do add here is added to the list of hostnames and IP Addresses and will be searched each time an Internet access is made by any computer on the LAN. I have added the address for the National Research Council of Canada atomic clock so that any computer on my LAN can use a program like Time868f to maintain its system clock.
