DHCP (Dynamic Host Configuration Protocol) is a method to distribute TCP/IP settings from a centralized server to computers on a network. The SonicWALL DHCP Server distributes IP addresses, gateway addresses and DNS server addresses to the computers on your LAN. Disable DHCP Server is the default setting in the SonicWALL.
If there is already a DHCP server located outside the SonicWALL Internet Security appliance, you can disable the DHCP server on the SonicWALL and allow the outside DHCP server to pass data through the SonicWALL. To enable this feature on the SonicWALL appliance, follow these steps:
Select Disable DHCP Server.
Select the Allow DHCP Pass Through check box.
Alert! Make sure there are no other DHCP servers on the LAN before you enable the DHCP server.
Tip! The SonicWALL DHCP server can assign a total of 254 dynamic and static IP addresses.
You can configure the SonicWALL DHCP Server to use dynamic IP address ranges and/or static IP addresses.
Dynamic Ranges are the ranges of IP addresses dynamically assigned by the DHCP server. The Dynamic Ranges should be in the same subnet as the SonicWALL LAN IP Address. To add dynamic IP address ranges, click on Add Range.
Static Entries, or static IP addresses, are typically assigned to servers that require permanent IP settings. To add a static entry, Click on Add Entry.
To remove a range of addresses from the dynamic pool, select it from the list of dynamic ranges, and click Delete Range. When the range has been deleted, a message confirming the update is displayed at the bottom of the browser window.
To remove a static address, select it from the list of static entries and click Delete Entry. When the static entry has been deleted, a message confirming the update is displayed at the bottom of the browser window.
