Make sure you assign a static IP address or use DHCP reservations to statically address the TRENDnet NVR/DVR. In your Router, forward the HTTP and RTSP ports to the NVR/DVR. By default the HTTP port is TCP port 80 and the RTSP port is TCP port 554. If you set a static IP address on the NVR/DVR please ensure your Router is configured as the default gateway and that you assign a DNS address. From a remote location you will use your Router's WAN IP address to access the NVR/DVR. If the TCP port is something other than 80, you will need to append the port number to the address with a colon then the port number. For example, https://500.87.985.30:81
