Auto Port Forward
To use an Auto Port Forward function, user’s router has to be supported UPNP function surely.
Auto Port Forward function is very useful because user doesn’t want to change a setting value of their
router and can set or change the port to the DVR system itself. However, please note that user has
to set again the port when the router is rebooted.
The default values are 5445 for port and 80 for web port. First of all, press a Show List button after
changing Auto Port Forward to OFF. Then, full list on the network will display. A Local IP and External
IP will display also. Check if there is the default value of 5445 and 80. If no, press an OK button after
changing Auto Port Forward to ON. If there is the default value of 5445 and 80 on the list, change the
default port numbers and press OK button after changing Auto Port Forward to ON. At that time, user
has to come out the SETUP menu after saving the value. Then, user can check to the System
Information menu in Live mode if the setting is success or not.
Network access beyond a router
In order to access the DVR remotely beyond a router (firewall), the user must open TCP port for
command level, live channels and storage channels. User need to open 2ports numbers on the router;
the DVR port number 5445 and the WEB port number 80.
If this port is not opened properly, user can not access DVR beyond a router.
