SonicWALL TZ 190 Manuale Utente

The SonicWALL security appliance includes a DHCP (Dynamic Host Configuration Protocol) 
server to distribute IP addresses, subnet masks, gateway addresses, and DNS server 
addresses to your network clients. The Network > DHCP Server page includes settings for 
configuring the SonicWALL security appliance’s DHCP server.

You can use the SonicWALL security appliance’s DHCP server or use existing DHCP servers 
on your network. If your network uses its own DHCP servers, make sure the Enable DHCP 
Server checkbox is unchecked.

The number of address ranges and IP addresses the SonicWALL DHCP server can assign 
depends on the model, operating system, and licenses of the SonicWALL security appliance. 
For example, on a SonicWALL TZ 170 SP Wireless running SonicOS Enhanced, the 
SonicWALL DHCP Server can assign a total of 64 address ranges with 64 IP addresses each 
or a total of 4,096 IP addresses.

that is stored in the options field of a DHCP message. When the DHCP message is sent to
