SonicWALL TZ 190 Manuale Utente

DHCP server persistence works by storing DHCP lease information periodically to flash 
memory. This ensures that users have predicable IP addresses and minimizes the risk of IP 
addressing conflicts after a reboot.

If you want to use the SonicWALL security appliance’s DHCP server, select Enable DHCP 
Server on the Network > DHCP Server page.

Select Enable Conflict Detection to turn on automatic DHCP scope conflict detection on each 
zone.
