DHCP Server Screening

This function allows users to not only to 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 first time the DHCP filter is enabled it will create both an access profile entry and an access rule per
port entry, it will also create other access rules. These rules are used to block all DHCP server packets. In
addition to a permit DHCP entry it will also create one access profile and one access rule entry the first
time the DHCP client MAC address is used as the client MAC address. The Source IP address is the
same as the DHCP server's IP address (UDP port number 67). These rules are used to permit the DHCP
server packets with specific fields, which the user has configured.
When DHCP Server filter function is enabled all DHCP Server packets will be filtered from a specific port.
