3.8.5 Network ports
When you connect one or more DVRs to a network through an IP sharing device, each DVR must be assigned a unique TCP port
number for access from outside the LAN. Additionally, the IP sharing device must be configured to forward the assigned port to the
specific DVR.
NOTE
This port number is listed next to the Port menu option in the Network Setup screen. If you access the DVR only from within the
same LAN, the TCP port number does not need to be changed.
