See the System chapter in the User's Guide for information on changing the operation mode of your
NBG7815.

1.3.1 Auto-IP Change

When the NBG7815 (A) gets a WAN IP address or a DNS server IP address which is in the same subnet as
the LAN IP address 192.168.123.1, Auto-IP Change allows the NBG7815 to change its LAN IP address to
10.0.0.1 automatically. If the NBG7815's original LAN IP address is 10.0.0.1 and the WAN IP address is in
the same subnet, such as 10.0.0.3, the NBG7815 switches to use 192.168.123.1 as its LAN IP address.
Figure 7 Auto-IP Change Example
Auto-IP Change only works under the following conditions:
• The NBG7815 must be in standard (router) mode for Auto-IP Change to become active.
• The NBG7815 is set to receive a dynamic WAN IP address.
