I searched, but nothing turned up, so.
When I port tested at GRC for the recent v3 update, something that didn’t happen in v2 happened:
1050 Ports Open
0 Ports Closed
6 Ports Stealth
1056 Ports Tested
NO PORTS were found to be CLOSED.
Ports found to be STEALTH were: 135, 136, 137, 138, 139, 445
Other than what is listed above, all ports are OPEN.
I’ve never cared much for Stealth, but I at least expected the ports to be closed.
That doesn’t look right. I have all but a couple ports disabled in Global Rules, and when the application that listens to these ports isn’t running, my PC looks completely stealth to GRC’s Shields Up.
What Firewall Security Level have you set?
What’s in your Global Rules?
No router, and my Firewall Security Level is Train With Safe Mode. Just installed, so.
IIRC, after installation CPFv3 didn’t have the last “blocking” global rule that would block any traffic not mentioned previously in the list (v2.4 did have it). So, “out of the box” it didn’t really block incoming connections on the system level. Check whether you have one there.
1050 open ports still look strange, though.
