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 G-1000 v2 is using the same LAN and WAN IP
addresses
The following figure shows an example where the G-1000 v2 is using a WAN IP address that
is the same as the IP address of a computer on the LAN.

Figure 92 IP Address Conflicts: CaseA

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.
Case B: The G-1000 v2 LAN IP address conflicts with the
DHCP client IP address
In the following figure, the G-1000 v2 is acting as a DHCP server. The G-1000 v2 assigns an
IP address, which is the same as its LAN port IP address, to a DHCP client attached to the
LAN.
