MX Mail Exchange Server Record
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.
