TELUS Wi-Fi Hub port forwarding causes Google Hello doorbell to disconnect

[news]

[wireless]

I have Google Nest Hello Doorbell camera software version 4110055 and a TELUS Wi-Fi Hub v3.00.24 build10.
If I port forward ANY port to any device on my local network, my Doorbell camera reports that it is offline. removing the port forward immediately puts the camera back online.

I'm not sure where to post this, if it's a problem with the nest, or a problem with the wifi router. I'm not sure if I should set up explicit port forwarding to the nest or how to even try to diagnose this. If anyone has suggestions it would be appreciated.

I'm attempting to forward ports 7777, 15777 and 15000 to my NAS which is running a game server, so my friends can connect. Looking up anything on the Nest doesn't seem to indicate it's using those ports.
