How to open ports

So I recently got Arlo and realized that the internet light is amber, which mean that there is no internet connection. I contacted support and they told me that I needed to open up ports 80, 123, and 443. I checked everywhere and I can't find how to open those ports up. I called for netgear support and he redirected me to arlo support, which did not help at all since arlo does not manage opening ports. After all this I decided to come to the community to see if some experts could help me with this, does anyone know how to open ports?
