Directed Broadcast
This checkbox sets whether the interface will forward 
network-prefix-directed broadcasts. This is a security feature which can help 
prevent your network from being used as an intermediary in certain kinds of 
attacks which use ICMP echo traffic (pings) or UDP echo packets with fake 
(i.e., “spoofed”) source addresses to inundate a victim with erroneous traffic.
 Options
The options button brings up the Ethernet TCP/IP Options Dialog Box which 
provides access to Proxy ARP, UDP Relays and other configuration informa-
tion. This dialog box is discussed later in this chapter.
OSPF
This option button brings up the OSPF Dialog Box which allows the OSPF 
routing protocol to be enabled. For more information on this dialog box and 
other OSPF parameters, refer to Chapter 15 - OSPF.
