Static entries are IP addresses assigned to servers requiring permanent IP settings. Because SonicOS allows multiple DHCP scopes per interface, there is no requirement that the subnet range is attached to the interface when configuring DHCP scopes.
To configure static entries, follow these steps:
Step 1In the Network > DHCP Server page, at the bottom of the DHCP Server Lease Scopes table, click Add Static. The Static Entry Configuration window is displayed.
General Settings
Step 2In the General tab, make sure the Enable this DHCP Scope is checked, if you want to enable this entry.
Step 3Enter a name for the static DNS entry in the Entry Name field.
Step 4Type the device IP address in the Static IP Address field.
Step 5Type the device Ethernet (MAC) address in the Ethernet Address field.
Step 6Type the number of minutes an IP address is used before it is issued another IP address in the Lease Time (minutes) field. 1440 minutes (24 hours) is the default value.
Step 7To populate the Default Gateway and Subnet Mask fields with default values for a certain interface, select the Interface Pre-Populate checkbox near the bottom of the page and choose the interface from the drop-down list. The populated IP addresses are in the same private subnet as the selected interface.
NoteTo select an interface from the Interface menu, it must first be fully configured and it must be of the zone type, LAN, WLAN, or DMZ, or be a VLAN sub-interface.
Step 8Use the populated gateway address or type the IP address of the gateway into the Default Gateway field.
Step 9Use the populated subnet mask or type the gateway subnet mask into the Subnet Mask field.
DNS/WINS Settings
Step 10Click the DNS/WINS tab to continue configuring the DHCP Server feature.
Step 11If you have a domain name for the DNS Server, type it in the Domain Name field.
Step 12Inherit DNS Settings Dynamically from the SonicWALL’s DNS settings is selected by default. When selected, the DNS Server IP fields are unavailable.
Step 13If you do not want to use the SonicWALL SuperMassive network settings, select Specify Manually, and type the IP address of your DNS Server in the DNS Server 1 field. You can specify two additional DNS servers.
Step 14If you have WINS running on your network, type the WINS server IP address(es) in the WINS Server 1 field. You can specify an additional WINS server.
Advanced Settings
Step 15Click on the Advanced tab. The Advanced tab allows you to configure the SonicWALL DHCP server to send Cisco Call Manager information to VoIP clients on the network.
Step 16Enter the IP address or FQDN of your VoIP Call Manager in the Call Manager 1 field. You can add two additional VoIP Call Manager addresses.
Step 17Under Network Boot Settings, in the Next Server field, enter the IP address of the PXE boot server (TFTP server) that a PXE client uses during the next stage of the boot process.
The fields under Network Boot Settings are used in a Pre-boot Execution Environment (PXE), in which the client boots up using files obtained over a network interface. The PXE client obtains the IP address and name of the PXE boot server, and the boot file name, from the DHCP server.
When using these options, select PXE under DHCP Generic Options.
Step 18In the Boot File field, type in the name of the boot file that the PXE client can get over TFTP from the PXE boot server.
Step 19In the Server Name field, type in the DNS host name of the PXE boot server (TFTP server).
Step 21Click OK to add the settings to the SonicWALL.
Step 22Click Accept for the settings to take effect on the SonicWALL.

Configuring DHCP Generic Options for DHCP Lease Scopes
This section provides configuration tasks for DHCP generic options for lease scopes.
NoteBefore generic options for a DHCP lease scope can be configured, a static or dynamic DHCP server lease scope must be created.
The DHCP Option Numbers provides a list of DHCP options by RFC-assigned option number.
To configure DHCP generic options for DHCP server lease scopes, perform the following tasks:
Step 1If modifying an existing DHCP lease scope, locate the lease scope under DHCP Server Lease Scopes on the Network > DHCP Server page and click the Configure icon, then click the Advanced tab. If creating a new DHCP lease scope, click the Advanced tab.
Step 2Select a DHCP option or option group in the DHCP Generic Option Group drop-down menu.
When the Network Boot Settings fields are configured for use with PXE, select PXE here.
Step 3To always use DHCP options for this DHCP server lease scope, check the box next to Send Generic options always.
Step 4Click OK.
