Figure 99 IP Address Conflicts: Case B

To solve this problem, make sure the G-1000 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 G-1000.

Figure 100 IP Address Conflicts: Case C

You must set the G-1000 to use different LAN and WAN IP addresses on different subnets if you enable DHCP server on the G-1000. For example, you set the WAN IP address to

192.59.1.1and the LAN IP address to 10.59.1.1. Otherwise, It is recommended the G-1000 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 G-1000 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 G-1000 DHCP server assigns to another subscriber acting as a DHCP client.
