Few days ago, I used Fling to check on my router and I realized that I have cisco stun-p1 1990 on a port. As I’m not sure if this is a malware, could somebody tell me what it is? I’m not sure if somebody has access to my line or not?
I don’t know this “fling” but if you are doing a port scan on the inside of your network (192.168.1.1, you are ) then you are looking at ports open on the inside of your router. Ports 1900and 5000 are for upnp, which is how your devices can open ports it needs to set up connections.
