33.4.1 WAN DHCP
DHCP functionality can be enabled on the LAN or WAN as shown in LAN & WAN DHCP.
LAN DHCP has already been discussed. The ZyAIR can act either as a WAN DHCP client (IP
Address Assignment field in menu 4 or menu 11.3 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.
Figure 197 LAN & WAN DHCP
The following table describes the diagnostic tests available in menu 24.4 for your ZyAIR and
associated connections..
