Configuring Static IP Addresses

Static entries are IP addresses assigned to servers requiring permanent IP settings.

Note: This screen is available at the unit/appliance level only.

To configure one or more static IP addresses, perform the following steps:

Select a SonicWALL appliance.
Expand the DHCP tree and click Static Entries. The Static Entries page displays

Do one of the following:

To enable the DHCP server, select the Enable DHCP Server check box.
To disable the DHCP server, deselect the Enable DHCP Server check box.

Select Enable Conflict Detection to turn on automatic DHCP scope conflict detection on each zone.
Do one of the following:

To enable the DHCP server persistence, select the Enable DHCP Server Persistence checkbox.
To disable the DHCP server persistence, deselect the Enable DHCP Server Persistence checkbox.

If server persistence is enabled, enter (in seconds) a DHCP server persistence monitoring interval.
To add or edit a static entry, do one of the following:

To add a static entry, click Add Static Entry.
To edit an existing static entry, click the icon in the Edit Static Entry column.

The DHCP Setup dialog for Static Entries is displayed.

In the DHCP Setup dialog box, on the General tab, complete the following fields:

Select the Enable this DHCP Scope check box to enable this static DHCP scope. Deselect it to disable the scope.
Type a descriptive name for this static DHCP entry in the Entry Name field.
Type the IP address of the device in the Static IP Address field.
Enter the Ethernet (MAC) address of the device in the Ethernet Address field.
In the Lease Time field, type the number of minutes that an IP address is used before it is re-issued. 1440 minutes (24 hours) is the default value.
Specify the IP address and subnet mask of the default gateway for this IP address in the Default Gateway and Subnet Mask fields. By default, these fields will use the settings on the Network Settings page.
Select the Interface Pre-Populate checkbox, and then select an interface from the drop-down menu.

Note: This checkbox is only available when adding a new DHCP Static Entry.

To add a static IP address, click Add Static Entry and complete the following fields:

Specify the IP address and subnet mask of the default gateway for this IP address in the Default Gateway and Subnet Mask fields. By default, these fields will use the settings on the Network Settings page.
Enter the lease time for this IP address in the Lease Time field.

Click the DNS/WINS tab.

In the DHCP Setup dialog box, on the DNS/WINS tab, complete the following fields:

If you have a domain name associated with this IP address, enter it in the Domain Name field.
To configure one or more DNS servers for this range, do one of the following:
To inherit DNS settings dynamically from the SonicWALL appliance’s DNS settings, click the Inherit DNS Settings Dynamically from the SonicWALL’s DNS settings checkbox.
To specify the DNS servers manually for this IP address, select Specify Manually and then type the IP address of your DNS Server in the DNS Server 1 field. You can specify two additional DNS servers.
If you have WINS running on your network, type the WINS server IP address in the WINS Server 1 field. You can add an additional WINS server.

For units running SonicOS Enhanced 4.0 and above, click the Advanced tab. This tab allows you to configure the SonicWALL DHCP server to send Cisco Call Manager information to VoIP clients on the network, and to configure DHCP generic options for lease scopes.

Enter 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. For more information about configuring VoIP, refer to the Configuring Voice over IP Settings.
Under 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.

In 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.
To configure a DHCP lease scope, select a DHCP option or option group in the DHCP Generic Option Group pull-down menu.
To always use DHCP options for this DHCP server lease scope, select the Send Generic options always checkbox.
When you are finished, click OK. The settings are saved. To clear all screen settings and start over, click Cancel.
