4-6-3. Network Port and Web Port
Connecting NSL through a common IP sharing device, each NSL must be assigned a unique TCP port
number for access from outside the LAN. This port number is displayed on NETWORK>NETWORK PORT
Setup MENU.
NOTE:
If you access the NSL only within the same LAN, the TCP port number does not need to
be changed.
Network access beyond a router
To access NSL beyond a router (firewall), you must open the proper TCP ports for live/playback streaming,
for commands, for remote backup, and for audio streaming. If these ports are not opened properly, you
can’t access the NSL beyond a router.
o For live/playback streaming, for commands, for remote backup: Open the port number
on NETWORK>NETWORK PORT menu. The default port number is 5445.
o For bi-directional audio: Open the port number on NETWORK AUDIO PORT. The default
port number is [NETWORK PORT number + 1].
o For web-viewer downloading and remote firmware upgrading: Open the port number on
NETWORK>WEB PORT menu. The default port number is 80.
o For IP Camera Setup through web viewer: Forward ports 59011 ~ 59254 to the NVR.
