Port 22 open

I have xfinity with a technicolor gateway and grc shields up is reporting port 22 ssh and port 443 open, not closed and not stealthed.

 

why would xfinity leave a port open on my gateway and how do I close it?

It's the very first remote access port that is programmed for shell line commands. It allows you to connect to your computer over the internet. More specifically it allows your computer to wake up after a command is sent. It's on by default so that most customers are satisfied with plug in and go router services. Otherwise if that person has IT knowledge they decide what to set up. Most of the time your computer doesn't even ever use it. Not to mention there are other ports that are open at some point. And closing it will not make your network more secure. Just consider it a luxury to have.

I mean. It's a message. That shield is just telling you that the port is open. Whether you close it is up to you. It's just doing itsi job and letting you know about it. 443 is also just internet. If you close that. Your computer will not even lose connection it will just go to other service like upnp and ipv6. And i doubt the shield will tell you that.

To be more specific. It's actually a luxury to have a router firewall on. In the past the firewalls were off. And only your computer firewall did the security job. You can turn off the firewall on your router all together and not use it.
