Grandstream Networks HT818 Administration Manual page 27

LAN DHCP Base IP Base IP Address for a LAN port. Default factory setting is 192.168.2.1. Note: When the
device detects WAN IP is conflicting with LAN IP, the LAN base IP address will be
changed based on the network mask -- the effective subnet will be increased by 1.
For example; 192.168.2.1 will be changed to 192.168.3.1 if net mask is 255.255.255.0.
Then the device will reboot
