DHCP functionality can be enabled on the LAN, DMZ, WLAN or WAN as shown in 

. LAN DHCP has already been discussed. The ZyWALL can act either as a 

WAN DHCP client (IP Address Assignment field in menu 4 or menu 11.x.2 is Dynamic and 
the Encapsulation field in menu 4 or menu 11 is Ethernet) or None, (when you have a static 
IP). The WAN Release and Renewal fields in menu 24.4 conveniently allow you to release 
and/or renew the assigned WAN IP address, subnet mask and default gateway in a fashion 
similar to winipcfg.
