Configuring Static DHCP Entries

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

Note: Static DHCP entries should not be configured for computers with IP addresses configured in Network

To configure static entries, follow these steps:

In 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

In the General tab, make sure the Enable this DHCP Entry is checked, if you want to enable this range.

Select the interface from the Interface menu. The IP addresses are in the same private subnet as the selected interface.

Enter a name for the static DNS entry in the Entry Name field.

Type the device IP address in the Static IP Address field.

Type the device Ethernet (MAC) address in the Ethernet Address field.

Type 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.

Select the gateway from the Gateway Preferences menu. The interface IP address is the default value, but you can select Other and type a different IP address for the gateway.

If you select the SonicWALL security appliance LAN IP address from the Gateway Preferences menu, the Default Gateway and Subnet Mask fields are unavailable. If you select Other, the fields are available for you to type the Default Gateway and information into the fields.

DNS/WINS

Click the DNS/WINS tab to continue configuring the DHCP Server feature.

If you have a domain name for the DNS Server, type it in the Domain Name field.

Inherit DNS Settings Dynamically from the SonicWALL's DNS settings is selected by default. When selected, the DNS Server IP fields are unavailable.

If you do not want to use the SonicWALL security appliance 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.

If 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.

VoIP Settings

Click on the VoIP Settings tab. The VoIP Settings tab allows you to configure the SonicWALL DHCP server to send Cisco Call Manager information to VoIP clients on the network.

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.

Click OK to add the settings to the SonicWALL.

Click Apply for the settings to take effect on the SonicWALL.

For more information on VoIP support features on the SonicWALL security appliance, see Chapter 28 Configuring VoIP Support.

Current DHCP Leases

The current DHCP lease information is displayed in the Current DHCP Leases table. Each binding entry displays the IP Address, the Ethernet Address, and the Type of binding (Dynamic, Dynamic BOOTP, or Static BOOTP).

To delete a binding, which frees the IP address on the DHCP server, click the Delete icon next to the entry. For example, use the Delete icon to remove a host when it has been removed from the network, and you need to reuse its IP address.
