You may also specify the forwarding servers; the Kanguru iNAS 100 will forward 
all DNS requests that can't be resolved locally to the specified DNS server 
(typically your ISP) and return the response to the client.  
Secondary DNS Server 
The Kanguru iNAS 100 can be configured as a secondary DNS server to provide 
redundant DNS service for your domain. 
•  Router and Firewall Configuration 
Routing Table 
The static route defines the network path to reach a specific network or host. You 
may need to set up a static route if this system is connected to more than one 
network.  
 
If you do not have other routers in the network, you will not need to add a static 
routing entry. The system will use the default routing table for communication 
between WAN and LAN. 
Virtual Server 
This feature allows you to make the service provided by the internal server 
accessible to the users from Internet. The Internet users will then use the WAN 
IP address of the Kanguru iNAS 100 to access all of your virtual servers. 
One-to one NAT 
This feature allows you to map an external public IP address to an internal 
private IP address hidden by NAT. To use this feature, you will need to have 
more than one public IP address from your ISP. You can use this feature to have 
several servers using internal IP addresses to be accessed from the Internet. 
Special Application 
This feature allows you to use some online applications that require 2-way 
communication or simultaneous sessions. If you use on-line games, 
conferencing or messaging software, you may need to configure this function. 
Web Site Filter 
The web site filter provides a mean to block access to undesirable web sites. If a 
web site address is added into a web site filter, access to that site is blocked for 
all clients in the internal LAN. 
Web Content Filter 
The web content filter allows you to block access to web sites with undesirable 
contents. 
Advanced Firewall Rule 
This feature allows administrators to define a set of rules to examine the network 
packet flow between internal LAN and external WAN. By default, all packets from 
external networks are denied except for web site requests. No packets from the 
internal network are blocked or discarded.
