Alarm.com With Xfinity Wifi Advanced Security

Are there any steps I need to take to ensure operation of Qolsys IQ & alarm.com when I enable Advanced Security (e.g., firewall) on my Xfinity router? Any port forwarding requirements? No cameras currently in use.

As far as I know u shouldn’t have any trouble with ADC cameras I use to have comcast a couple years ago didn’t have any issues with the ADC cameras

In general no, you’re not likely to impact the panel, and there is no port forwarding to set up.
