You must set the ZyAIR to use different LAN and WAN IP addresses on different subnets if
you enable DHCP server on the ZyAIR. For example, you set the WAN IP address to
192.59.1.1 and the LAN IP address to 10.59.1.1. Otherwise, It is recommended the ZyAIR use
a public WAN IP address.

Case D: Two or more subscribers have the same IP address.
By converting all private IP addresses to the WAN IP address, the ZyAIR allows subscribers
with different network configurations to access the Internet. However, there are situations
where two or more subscribers are using the same private IP address. This may happen when a
subscriber is configured to use a static (or fixed) IP address that is the same as the IP address
the ZyAIR DHCP server assigns to another subscriber acting as a DHCP client.
