When I install CIS I used ShieldsUP! to check my firewall Vulnerability and port 135 was open when I tested Comodo firewall with ShieldsUP! at https://www.grc.com/x/ne.dll?bh0bkyd2 here’s how to fix it go to firewall in CIS then go to Stealth Port Wizard and check the box that says block all incoming connections stealth my ports to everyone
Okay, this looks good. My guess is that there is an other device between your pc and Shields up that is causing this.
Probably your internet modem/router or an other pc on the local network.
Can you tell us a little bit more about your setup ?
Allow IP OUT from IP ANY to IP ANY where protocol is ANY
All outgoing traffic is global allowed, From ANY source ip (your computer) to ANY source ip (not your computer) for all protocol’s IP,TCP,UDP, IGMP etc etc.
Following 2 allow incoming Fragmentation needed and Traceroute response messages.
Last one is blocking and logging all incoming traffic to your computer.
So Shields up should be in your logfiles if the detection is caused by your pc.
Do you have access to the cable modem ? webinterface or so ?
Maybe a manual, or can you check if it’s having an active firewall.
An other thing you can try is to create a global rule that explicitly denies the traffic to port 135.
Create a global rule Block, Tick the log option, Protocol = TCP, Direction = IN, Destination port = single port 135
Apply, now move it to the top of the policy Press Apply and then test again with Shields up.
If it’s your pc responding to shields up it should at least show up in the logging being blocked.
