Hello. If I check my static external IP address on https://www.yougetsignal.com/tools/open-ports/
It says that port 22 is open on it.
ISP is plugged to my Cisco 2901.
How do I make sure the port 22 (SSH) is not open to public?
I tried following suggestions I found on other discussions here but couldn't succeed. I'm not an expert at all here.
Could someone please assist?
