10.1 Time Settings
This section ass
ists you in setting the device’s system time; you can
either select to set the time and date manually or automatically obtain the
GMT time from Internet.
Note
: The configured time settings lose once the router is powered
off. But it obtains the GMT time automatically when you connect it to the
Internet. Features/functions based on time (e.g. security settings) take
effect only after time settings are configured manually or updated
automatically from Internet.
10.2 DDNS
Dynamic DNS or DDNS is a term used for the updating in real time of
Internet Domain Name System (DNS) name servers. We use a numeric IP
address allocated by Internet Service Provider (ISP) to connect to Internet;
the address may either be stable ("static"), or may change from one
session on the Internet to the next ("dynamic"). However, a numeric
address is inconvenient to remember; an address which changes
unpredictably makes connection impossible. The DDNS provider allocates
a static hostname to the user; whenever the user is allocated a new IP
address this is communicated to the DDNS provider by software running
on a computer or network device at that address; the provider distributes
the association between the hostname and the address to the Internet's
DNS servers so that they may resolve DNS queries. Thus, uninterrupted
access to devices and services whose numeric IP address may change is
maintained.
