Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname. This
dynamic IP address is the WAN IP address. For example, to use the service, you must first apply
for an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers are
supported.
Quality of Service (QoS)
QoS gives you full control over which types of outgoing data traffic should be given priority by the
router, ensuring important data like gaming packets, customer information, or management
information move through the router ay lightning speed, even under heavy load. The QoS features
are configurable by source IP address, destination IP address, protocol, and port. You can throttle
the speed at which different types of outgoing data pass through the router, to ensure P2P users
don't saturate upload bandwidth, or office browsing doesn't bring client web serving to a halt. In
addition, or alternatively, you can simply change the priority of different types of upload data and let
the router sort out the actual speeds.
IPv6 supported
Internet Protocol version 6 (IPv6) is a version of the Internet Protocol that is designed to succeed
IPv4.
IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address,
whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038)
addresses. This expansion provides flexibility in allocating addresses and routing traffic and
eliminates the primary need for network address translation (NAT), which gained widespread
deployment as an effort to alleviate IPv4 address exhaustion.
IPv6 also implements new features that simplify aspects of address assignment (stateless address
autoconfiguration) and network renumbering (prefix and router announcements) when changing
Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the
host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the
host identifier from Link Layer media addressing information (MAC address).
Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security
(IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4
(into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a
fundamental interoperability requirement.
Virtual Server ("port forwarding")
Users can specify some services to be visible from outside users. The router can detect incoming
service requests and forward either a single port or a range of ports to the specific local computer
to handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and
expose it to the outside network. Outside users can browse inside web servers directly while it is
protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside
network, Internet.
Rich Packet Filtering
Not only filters the packet based on IP address, but also based on Port numbers. It will filter
packets from and to the Internet, and also provides a higher level of security control.
