DDNS
The router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a
fixed host and domain name to a dynamic Internet IP Address. It is useful when you are
hosting your own website, FTP server, or other server behind the router.
Before using this feature, you need to sign up for Dynamic DNS service from one of the
listed providers.
Each provider requires a slightly different configuration, so you may need to consult your
DDNS provider’s website to confirm how to set your router up.
Port Mapping
Port mapping is a useful method for mapping a particular physical port to a particular ATM
virtual circuit. If you are using a ATM VC connection to provide an isolated channel, you
will be able to use this function to allocate a particular Ethernet (or WLAN) port as an
endpoint to this channel.
