Strict firewall settings

Hi all, I recently installed a bunch of ring security products and in the process had to lower my firewall settings for the cameras to function. I’m inquiring to find out how to increase my firewall security without hindering the camera functionality. When I reached out to Ring customer service, they told me that hacking was not Ring’s problem, but the internet providers, yet this is ironic because it’s their products that are making me lower my security settings. Both my internet provider and Ring are pointing fingers at each other and it’s not helpful. Thank you for any insight!
