Smart DHCP

A smart traffic filtering option that allows a Dynamic Host Configuration Protocol (DHCP) client to receive an IP address from a DHCP server while protecting the client against DHCP attacks from a network. If a Symantec Protection Agent sends a DHCP request to a DHCP server, it waits for five seconds to allow for an incoming DHCP response. If a Symantec Protection Agent does not send a DHCP request to a DHCP server, then Smart DHCP does not allow the packet. Smart DHCP does not block packets. It simply allows the packet if a DHCP request was made. Any other DHCP blocking or allowing is done by the normal security rule set. See also Dynamic Host Configuration Protocol (DHCP).
