37.5.1 WAN DHCP
DHCP functionality can be enabled on the LAN or WAN as shown in Figure 304 . 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.
