Notes:

  • This article is applicable to ScreenOS 5.0 and higher. 
  • This article is not applicable to ISG1000, ISG2000, NS5200, and NS5400.
  • DHCP server is not supported on ISG1000, ISG2000, NS5200, and NS5400.

To configure your NetScreen as a DHCP server, perform the following steps:

  3. From Configure, click Edit.

  4. From the DHCP list, click to select DHCP Server.

  5. From the DHCP server settings menu, enter the values that your NetScreen will assign to DHCP clients:

    • Gateway: This address will be used by the DHCP clients as the default gateway.
    • Netmask: This is the subnet mask that will be used by the DHCP clients.
    • DNS#1: This address will be used as the primary Domain Name Server by the DHCP clients.
    • WINS#1: This address will be used as the primary Windows Internet Naming Server by the DHCP clients.
  6. Click Apply.

    Note: You will now see three additional options.
  7. From the additional options list, click Addresses.

  8. From the DHCP Server Address List page, click New.

  9. From the IP Address Start text box, enter the beginning IP address of the DHCP range, and from the IP Address End text box, enter the ending IP address of the DHCP range.
