In addition to specifying the port number used, you also need to specify the protocol used. The
protocol is determined by a particular application. Most applications use TCP or UDP, however you
may also specify other protocols using the drop-down Protocol menu. Setting the protocol to “all”
causes all incoming connection attempts using all protocols on all port numbers to be forwarded to
the specified IP address.
DMZ
The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP
address as the DMZ Host, all incoming packets that do not use a port number which is already used
by any other Virtual Server entries will first be checked by the Firewall and NAT algorithms before it
is passed to the DMZ host. When this is done, press Apply to save the changes.

One-to-One NAT
One-to-One NAT maps a specific private/local address to a global/public IP address.
If you have multiple public/WAN IP address from your ISP, you are eligible for One-to-One NAT to
utilize these IP addresses.
WAN IP Pool:
select Enable to activate the feature and Click Apply to submit your configuration.
WAN Port:
choose the WAN port you are going to configure multiple IPs for One-to-One NAT.
for example, you have three available public IPs from 172.16.1.103-172.16.1.105 (internal test for
instance), you can add these IPs respectively to the following IP Address field.
IP Address:
Type each available WAN IPs to this field and Click Add to add respectively to show
as below.
Then Click
to go on distributing the WAN IP to the specific local IP.
Global IP Address:
the set WAN IP, you can type manually or select if you have add to the list
before.
Internal IP Address:
set the concrete local IP you want to map to the WAN IP.

Time Schedule
The Time Schedule supports up to 16 time slots which helps you to manage your Internet connection.
In each time profile, you may schedule specific day(s) i.e. Monday through Sunday to restrict or
allow the use of the Internet by users or applications.
Time Schedule correlates closely with router time. Since router does not have a real time clock
on board, it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP
server. Refer to Time Zone for details. Your router time should correspond with your local time. If the
time is not set correctly, your Time Schedule will not function properly.
