Network Protocol (IP) Menu (Continued)

Parameter	Description
IP MTU	Assigns the size of the Maximum Transmission Unit for the interface. This
	determines whether or not a given IP datagram is fragmented.
NAT	Determines the type of IP address if NAT is being used. Use Global otherwise.
	See chapter 11 or the examples in chapter 4 for details on how to configure NAT.
ICMP Port	Active causes the router to send ICMP Port Unreachable messages when it
	receives UDP or TCP messages for ports that are not recognized. This type of
	message is used by some traceroute applications, and if disabled, the router might
	not be identified in the traceroute output. However, there are security and
	performance reasons to leave this option Inactive.
Incoming Rule List	Filter rule list for incoming packets. See chapter 12 for instructions on how this
	parameter should be set.
Detailed Incoming IP	Applies when a list is selected in the previous parameter. See explanation of IP
Accounting	Accounting later in this chapter. IP Accounting for a rule requires that the
	parameter CONFIG =>RULES LIST=>IP=>CONFIGURE RULES=>ADD RULE
	=>ALLOW ACCOUNT PROCESS also be Yes.
Outgoing Rule List Name	Filter rule list for outgoing packets. See chapter 12 for instructions on how this
	parameter should be set.
Detailed Outgoing IP	Applies when a list is selected in the previous parameter. See explanation of
Accounting	Detailed Incoming IP Accounting.
Routing of Broadcast	Activating this parameter causes the router to route broadcast messages from the
Messages	LAN to the WAN and vice-versa. An individual interface can be excluded by setting
	this parameter to Inactive, without effecting the broadcast of messages on the other
	interfaces.
