User provisioning for DDNS

The user needs to have an account in the DDNS server. The hostname and the public IP of
the eRouter will be configured in the DDNS server for the given account. In the Web UI, the
user has to select the DDNS service provider URL, credentials of the account to log into the
URL and the predefined hostname.

DMZ

The DMZ feature exposes the network user to the Internet for using special-purpose services
such as Internet Gaming or Video Conferencing. DMZ hosting forwards all the ports at the
same time to one computer. The Port Forwarding feature is more secure because it only
opens the ports the user want to have opened, while DMZ hosting opens all the ports of one
computer, exposing the computer to the Internet. This is generally used if PCs are running
specific applications that use random unknown port numbers and do not function correctly
with specific port triggers or port forwarding setups. It is advisable not to have any
PCs/Servers as DMZ hosts because of exposure to the public internet which results from
this configuration. Remember to disable this setting if this is enabled temporarily for any
specific application.
Any computer whose port is being forwarded must have its DHCP client function disabled
and should have a static IP address assigned to it because its IP address may change when
it is using the DHCP function.
