Appendix F

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

In the following figure, the ZyAIR is acting as a DHCP server. The ZyAIR assigns an IP

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