Settings
TCP
Send RSTs	RST is a TCP control bit that informs the receiving TCP stack to
	end a connection immediately. However, sending this bit may
	pose a security risk. Select whether you want the RST control bit
	sent to end a connection immediately. Choices are:
	On = the RST bit is sent. (default)
	Off = the RST bit is not sent.
	After selecting an option, click Submit.
ICMP	Internet Control Message Protocol (ICMP) can be used as an
	error-reporting protocol between two hosts. This setting specifies
	whether incoming and outgoing ICMP messages are processed.
	Choices are:
	On = ICMP messages are processed. (default)
	Off = ICMP messages are not processed.
	After selecting an option, click Submit.
ARP	Enter the maximum number of seconds that a MAC address will
	remain in cache before being removed. Default is 60 seconds.
	After selecting an option, click Submit.
ARP Cache
IP Address	Enter the IP address of the entry to be added to the Address
	Resolution Protocol (ARP) cache.
MAC Address	Enter the MAC address of the entry to be added to the ARP
	cache. After entering an IP address and a MAC address, click
	Submit.

IP Address Filter Page

Clicking the IP Address Filter link in the menu bar displays the IP Address Filter page. Here you can specify the IP addresses and subnets allowed to send data to the EDS. All packets sent from IP addresses not on this list are ignored and discarded. By default, the IP address list is empty, so all addresses are allowed.

The network mask and IP address settings you specify on this page determine the range of IP addresses that can access the EDS. For example:

‹An IP address of 10.0.0.0 and a network mask of 255.0.0.0 allows any device with an IP address in the 10.x.x.x range to access the EDS.

‹An IP address of 192.168.1.1 with a network mask of 255.0.0.0 causes the EDS to allow all IP addresses in the range of 192.x.x.x.

‹An IP address of 192.168.1.1 with a network mask of 255.255.255.0 only allows IP addresses in the range of 192.168.1.x to access the EDS.
