The vast majority of Montavue users will not need to forward any ports as long as they are accessing their NVR by its serial number rather than The IP address.
For those users who need to do so due to a complicated local network configuration, the following ports will need to be forwarded to remotely access your NVR:
TCP: 37777
UDP: 37778
HTTP: 80
RTSP: 554
HTTPS: 443
Check with your ISP to make sure that these are port forwarded on your router, and use canyouseeme.org to test the ports above while on the phone with them to confirm if it worked or not.
The Ports that matter most are Port 80 and Port 37777
