Port Forwarding for Arlo Base Station with a T3200M modem

Hello,

I bought an Arlo base station to avoid paying the monthly fees to use their cloud storage but in order to view the video that is saved to the base station I need to set up port forwarding.  I have a Telus T3200M modem and have followed all the instructions from Arlo to enable port forwarding but it is not working.  I was logged into the Telus Modem account page and put in the WAN & LAN numbers that the Arlo app generated - the changes show as applied on the Telus page but they are not working with the Arlo app.  I tried contacting Telus tech support but they are not trained in helping with this.  I'm hoping someone knows how to do this.  I also see that it would be advisable to set up a VPN.  I'm hoping that someone can explain how to set up the VPN and port forward.  

Thank you!
