Dynamic DNS
Dynamic DNS
The ISP often provides you with a dynamic IP address when you connect to the Internet via
your ISP. It means that the public IP address assigned to your router changes each time you
access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic
WAN IP address. It allows the router to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the router is online, you will be able to use the
registered domain name to access the router or internal virtual servers from the Internet. It
is particularly helpful if you host a web server, FTP server, or other server behind the
router.
Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the
DDNS service providers. The router provides up to three accounts from three different DDNS
service providers. Basically, Vigor routers are compatible with the DDNS services supplied by
most popular DDNS service providers such as www.dyndns.org, www.no-ip.com,
www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com. You should visit
their websites to register your own domain name for the router.
LAN DNS / DNS Forwarding
LAN DNS / DNS Forwarding
The LAN DNS lets the network administrators host servers with privacy and security. When
the network administrators of your office set up FTP, Mail or Web server inside LAN, you can
specify specific private IP address (es) to correspondent servers. Thus, even the remote PC
is adopting public DNS as the DNS server, the LAN DNS resolution on Vigor2762 Series will
respond the specified private IP address.
Schedule
Schedule
The Vigor router has a built-in clock which can update itself manually or automatically by
means of Network Time Protocols (NTP). As a result, you can not only schedule the router to
dialup to the Internet at a specified time, but also restrict Internet access to certain hours
so that users can connect to the Internet only during certain hours, say, business hours. The
schedule is also applicable to other functions.
UPnP
UPnP
The UPnP (Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers,
the major feature of UPnP on the router is "NAT Traversal". This enables applications inside
the firewall to automatically open the ports that they need to pass through a router.
Wake on LAN
Wake on LAN
A PC client on LAN can be woken up by the router it connects. When a user wants to wake
up a specified PC through the router, he/she must type correct MAC address of the specified
PC on this web page of Wake on LAN (WOL) of this router.
In addition, such PC must have installed a network card supporting WOL function. By the
way, WOL function must be set as "Enable" on the BIOS setting.
