To solve this problem, make sure the G-1000 v2 LAN IP address is not in the DHCP IP 
address pool. 

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 v2. 

Figure 94   IP Address Conflicts: Case C

You must set the G-1000 v2 to use different LAN and WAN IP addresses on different subnets 
if you enable DHCP server on the G-1000 v2. 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 G-1000 v2 
use a public WAN IP address.

By converting all private IP addresses to the WAN IP address, the G-1000 v2 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 v2 DHCP server assigns to another subscriber acting as a DHCP 
client.

In this case, the subscribers are not able to access the Internet.
