TG862G/CT & TG862R: LAN Subnet Setup

The TG862 also includes configurable options for the Local Area Network (LAN).  The LAN IP Address and DHCP range can be configured and modified to suit the needs of the network.  By default, the LAN IP address of the TG862 is 10.0.0.1, and DHCP for the LAN network is enabled.  This document describes how to change the LAN IP address and DHCP range of the TG862.

NOTE: If the LAN IP address is modified to be in a different subnet (e.g. 192.168.0.1), the TG862 will automatically change the DHCP range to use addresses in that subnet.
