Question
How do I configure the LAN settings in the SBG6782?

Answer
The SBG6782 includes configurable options for the Local Area Network (LAN), in which the LAN IP Address and DHCP range can be modified to suit the needs of the network.  By default, the LAN IP address of the SBG6782 is 192.168.0.1.  This document describes how to change the LAN IP address and DHCP range of the SBG6782. 

Changing the Local Area Network (LAN) IP Address

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter http://192.168.0.1 into the address box, and press the Enter key.  The Login page appears.
     
    NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.
     
  2. On the Login page:
    a.   Enter admin in the Username field.
    b.   Enter motorola in the Password field.
    c.   Click the Login button.  The Home page appears.
     
     
    Right click on the image to save it to your computer.
     
  3. Move the mouse-cursor over the Basic tab and select the DHCP sub-link.  The Basic - DHCP page appears.
  4. On the Basic - DHCP page:
    a.   LAN IP Address - Enter the desired IP address for the LAN interface here.  In this example, 192.168.8.1 is used. 
     
    NOTE: The LAN IP address used must be a private IP address (within one of the following ranges):
     
    10.0.0.x - 10.255.x.x
    172.16.x.x - 172.31.x.x
    192.168.x.x - 192.168.x.x
     
    b.   Scroll down to the bottom of the page, and click the Apply button.
     
     
    Right click on the image to save it to your computer.

     
  5. Next, the following message will appear (below).  After waiting a few moments, click the RELOAD link to go back to the Login page. 
     
    NOTE 1: If the LAN IP address is modified to be in a different subnet (e.g. 192.168.8.1), the SBG6782 will automatically change the DHCP range to use addresses in that subnet.
     
    NOTE 2: The subnet mask of the SBG6782 (255.255.255.0) cannot be modified

Configuring the DHCP settings

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter http://192.168.0.1 into the address box, and press the Enter key.  The Login page appears.
     
    NOTE: By default the LAN IP address is 192.168.0.1.  If the default address has been changed, enter the custom address in the address box.
     
  2. On the Login page:
    a.   Enter admin in the Username field.
    b.   Enter motorola in the Password field.
    c.   Click the Login button.  The Home page appears.
     
     
    Right click on the image to save it to your computer.

     
  3. Move the mouse-cursor over the Basic tab and select the DHCP sub-link.  The Basic - DHCP page appears.
     
     
    Right click on the image to save it to your computer.

     
  4. Enable DHCP Server:
    • If it is desired to have the SBG6782 give IP addresses to all of the devices automatically, leave this setting at Enabled.
    • If some devices are manually configured with IP addresses, but others are to receive an address from the SBG6782, leave this setting at Enabled.
    • If there is another device on the network that will be the DHCP server, uncheck the Enabled option.
    • If it is desired to manually configure each device with an IP address, uncheck the Enabled option.
    NOTE: If the DHCP Server option is set to unchecked, skip down to step 8.
     
  5. Starting Local Address - This setting classifies the first IP address to be used in the DHCP range.
  6. Max Number of Network Devices - This will classify how many IP addresses are to be used in the DHCP range.  For example, if this option is set to 100, and the Starting Local Address is set as 192.168.0.100, then the DHCP range will be from 192.168.0.100 - 192.168.0.199.
  7. Lease time - This is the amount of seconds that a device will keep an IP address, if that device has received an IP address automatically from the SBG6782.
  8. Click the Apply button.
