3-8-1. Ports
When you connect one or more DVRs to a network through an IP sharing device, each device must have a
unique TCP port number for access to each unit from outside the LAN. Also, the IP sharing device must be
configured for port forwarding so when each port is accessed on the IP sharing device, it will forward to the
appropriate DVR.
Note: This port number is listed next to the Port menu option in the Network Setup screen. If you plan to
access the DVR units only from within the same LAN, the TCP port does not have to be changed.

Network access beyond a router
In order to access the DVR remotely beyond a router (firewall), the user must open one TCP port for
command level, live channels and storage channels. If this port is not opened properly, user can not
access DVR beyond a router.
If the DVR port number is set to 5445, open the TCP port 5445 on the router.
