IP Address Assignment Conflicts
This appendix describes situations where IP address conflicts may occur. Subscribers with
duplicate IP addresses will not be able to access the Internet.
Case A: The ZyAIR is using the same LAN and WAN IP
addresses
The following figure shows an example where the ZyAIR is using a WAN IP address that is
the same as the IP address of a computer on the LAN.
Figure 129 IP Address Conflicts: CaseA
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 B: The ZyAIR LAN IP address conflicts with the DHCP
client IP address

address, which is the same as its LAN port IP address, to a DHCP client attached to the LAN.
