I have had a few notices recently saying one of my devices may have an SNMP vulnerability. I have checked for rules in the hub 3 settings to delete that use ports 161/2 but the only one there does not allow me to delete it. The IP address that has automatically created it is from my CCTV system which I assume is to allow me to view remotely. I cannot see anything in the CCTV settings where port 161 is mentioned to change it. Is there a way I can block the port completely to stop getting more notices through? Thanks
I have done all of that but there are no rules I can delete. As in my original post the only thing that mentions port 161 is an automatic rule generated from an IP that is my CCTV system - there is nothing in my CCTV settings that shows port 161 being required so cannot remove it there either. Stumped!
So it looks like the CCTV is setting that up which is why you getting the messages. As you have done everything on your side and the hub the next point off call would be the manufacture of the CCTV system as from what you have said it is basically phoning home.
I have a good look around and cannot find anything else that could stop it, maybe a VM staff member would like to comment.
