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.
