Auto-IP Change
When the NBG7815 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.

Auto-IP-Change only works under the following conditions:
The NBG7815 must be in Standard Mode (see Section 13.7 on page 140 for more information) for Auto-
IP-Change to become active.
