DDNS
This free service is very useful when combined with the LG DDNS Server.
It allows the user to connect the IP device using the URL, rather than an
IP Address. This also solves the problem of having a dynamic IP address.

> Use DDNS server: Enable the DDNS function.
- Provider: Displays the DDNS provider.
- Hostname: Enter the hostname you want to use.

IP filtering
The access of the IP addresses in the list are allowed or denied according
to the choice made in the drop-down list of the Basic policy option.
The administrator can add up to 10 IP address entries to the list (a
single entry can contain multiple IP addresses). The users from these
IP addresses need to be specified in the user list with the appropriate
access rights. The IP list is to control the access permission of clients by
checking the client IP address.
IP list
> Basic policy: Select the basic policy type.
- Allow all: Allow all the IP address basically, but the IP
addresses in the list are denied.
- Deny all: Deny all the IP address basically, but the IP
addresses in the list are allowed. It needs at least one IP
address to activate this function.
