SBG6782 (v8.4.x): IP Address Reserve Setup

How do I reserve an IP address in the SBG6782?

In certain scenarios, it may be desired to have a client receive a particular IP address from the SBG6782, and always keep that address without having to manually configure a static IP address in the client.  This can be accomplished with the Reserve New IP Address feature in SBG6782.  The SBG6782 can be configured to reserve a specific IP address within the DHCP range of addresses for a specific client.  When the client connects to the SBG6782, it will receive the IP address automatically that it has been reserved for.

NOTE: This option serves as a great solution for devices that are configured to use the Port Forwarding or DMZ options in the SBG6782.

By default, no IP addresses are reserved in the SBG6782.  This document describes how to reserve and unreserve an IP address for a particular client.
