IP Address Conflicts: Case B
To solve this problem, make sure the ZyXEL Device LAN IP address is not in the DHCP IP
address pool.
Case C: The Subscriber IP address is the same as the IP
address of a network device
The following figure depicts an example where the subscriber IP address is the same as the IP
address of a network device not attached to the ZyXEL Device.
Figure 283
IP Address Conflicts: Case C
You must set the ZyXEL Device to use different LAN and WAN IP addresses on different
subnets if you enable DHCP server on the ZyXEL Device. 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
ZyXEL Device uses 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 ZyXEL Device 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 ZyXEL Device DHCP server assigns to another subscriber acting as a
DHCP client.
In this case, the subscribers are not able to access the Internet.
