DHCP Server Screening Settings

This function allows the user to not only restrict all DHCP Server packets but also to receive any specified DHCP
server packet by any specified DHCP client, it is useful when one or more DHCP servers are present on the network
and both provide DHCP services to different distinct groups of clients.
The DHCP Server Screening folder contains two windows: DHCP Server Screening Port Settings and DHCP Offer
Permit Entry Setting.
